Why does your expectation differ here compared to the following:
MyAwesomeThing.prototype.myCoolFunction = function() {
var cachedHotness = gensym();
if (!this[cachedHotness])
this[cachedHotness] = doExpensiveThing(this)
return this[cachedHotness];
}
Is it because |private cachedHotness;| does not "look generative"?
I agree with Oliver: the private keyword is going to cause confusion.
It looks like it is declaring something, not generating something.
A small step toward making the proposed syntax less Java-like (and
therefore less likely to cause confusion) might be:
use private cachedHotness;
A use directive feels vaguely more comfortable here to me. It makes it
clearer to the programmer that some kind of magic is going on.
But I confess that I haven't actually read Allen's proposal, so take
this with a grain of salt.
