Any reason I couldn't create a language supporting infix, postfix, and prefix functions, and more?

wish helps you This is not too hard to do. You'll want to assign each operator a fixity (infix, prefix, or postfix) and a precedence. Make the precedence a real number; you'll thank me later. Operators of higher precedence bind more tightly than operators of lower precedence; at equal levels of precedence, you can require disambiguation with parentheses, but you'll probably prefer to permit some operators to be associative so you can write
x + y + z
prefix (e) postfix

Invoking nested functions in the Dart programming language

hop of those help? I defined an inner function here: , You can declare the function outside the enclosing block:
void main() {
  var fullName;
  person(firstName, lastName){
      fullName = () => "firstName: $firstName lastName: $lastName";
  }
  person("Rob", "Rock");
  print(fullName());
}
void main() {
  person(firstName, lastName) => () => "firstName: $firstName"
                                       "lastName: $lastName";
  print(person("Rob", "Rock")());
}
class Res{
  var _firstName, _lastName;
  Res(this._firstName, this._lastName);
  fullName() => "firstName: $_firstName lastName: $_lastName";
}
void main() {
  person(firstName, lastName) => new  Res(firstName,lastName);
  print(person("Rob", "Rock").fullName());
}

TypeScript - building .d.ts definition files - Nested functions.

I wish this helpful for you I am in the process of creating TypeScript definitions for RiotJS. This lib uses nested functions like so: , Here is an implementation that uses inline typing :
declare var riot: {
    route: {
        (callback: Function): void
        parser: {
            (args): any;
        }
    };

}

riot.route(() => null); // function
riot.route.parser(1); // function in function
interface Riot {
    route: {
        (callback: Function): void
        parser: {
            (args): any;
        }
    };

}
declare var riot:Riot;

riot.route(() => null); // function
riot.route.parser(1); // function in function
interface Riot {
    route: {
        (toOrCallback: string|Function): void
        (callback: Function): void
        parser: {
            (args): any;
        }
    };

}

Atom Language Definition using nested Regex patterns

wish helps you I am actually trying to define a grammar in Atom (which goes surprisingly well) and, after 3 days of fiddling with Regex, get the feeling to slowly going nuts. , This regex below uses recursion:
(?<=\s)\w+(\(((?:[^()]+|(?1))*?)\))(\('.*?'\))?
  foo( a(1) )
  bar(1)('a')
  foo( bar(1)('a') )
  foo( bar(1)('a')('a') )('a')
(?<=\s)\w+\((?:.*?(?:\(.*?\))?)+\)(?:\('.*?'\))?

Passing arguments to nested functions with ellipses in R language

will be helpful for those in need As @Dason proposed:" I never said anything about the fock function. That isn't where the issue is. The issue is in your line a <- sapply(paste(..., sep=" "), fock). In that paste statement there is a sep being passed in through the dots and then another sep being specified. You either need to remove the sep from the dotlist manually or have it be a different argument that is passed in in which case it will never be in the dotlist to begin with"
