There is also an alternate version I was thinking of: Simply return function(){} string in all case so, thus not listing what arguments does a function have. This case the code will be more simple as that would be just a magic string get and return.

I think, the version is preferable for now, since anyway we do not reconstruct function's code.
This would also reduce engine's binary size.

@egavrin, what do you think about this?

Updated to return a simple function(){} string.

@ruben-ayrapetyan smaller binary is better ^_^. Anyway, it's not critical, we may change it later at optimization stage, if needed.
