Package: Lambda

  This mod hacks syntactic sugar for "lambda functions" into Lua by simply loading and caching strings containing Lua code via the (global!) l function.

  Unfortunately, the way this is done has too many drawbacks to be viable:

  • You lose anything static that operates on the code - syntax highlighting, static analysis, formatting, etc.
  • You lose syntax checking at load time - you can now get syntax errors at run time.
  • You lose upvalues, which often play a very important role when lambdas are involved.
  • You may lose some performance.
  • You may lose programmers - who will have to look up where l comes from (and why it should be used).

  Just bite the bullet and instead of l"(...) ...", write function(...) return ... end.

  If you can't take Lua not having enough syntactic sugar for you anymore, find an established Lua preprocessor that works for you and roll with that.
