Closures that are modified (like objects) are mistaken for static functions

[JobLeonard]

In general plugin speeds up my code-base quite a bit, but in one crucial part it breaks my (admittedly quite unusual) code: the part where I generates a recursive tree of functions. ~~I found a work-around~~, but I think this counts as a bug.

The part of the code in question that breaks is this:

//== INPUT
export function vectorOf(patternArr){
	let retVal= function(){};
	retVal.encoder = encodeVector(patternArr);
	retVal.decoder = decodeVector(patternArr);
	return retVal;
}

//== OUTPUT, functionally different:
function _retVal2() {}

function vectorOf(patternArr) {
	var retVal = _retVal2;
	retVal.encoder = encodeVector(patternArr);
	retVal.decoder = decodeVector(patternArr);
	return retVal;
}

(note that I have already removed the fat arrow syntax, but the problem remains)

The problem is that vectorOf should return newly instantiated function object whenever it is called, instead of modifying a static one. I understand that the whole point of this plugin is turn closures into the latter, but the part where I modify the function object breaks that :P

EDIT: my workaround didn't work, turns out I forgot to turn on the closure-elimination plugin while testing.

You may can be avoid the problem by new Function() first.

I think this problem involves the main feature, so it may be difficult to fix. Maybe we can use some comment rule in line to avoid transform? @Gvozd @phpnode

Ah, I'll try that!

Maybe I should just switch to old-school prototypical inheritance and use instanceof. It might actually perform better here too (not that this code was a bottleneck).

But I think a comment rule to prevent transformations on a section of code would be a useful feature to have anyway!
