This one trips everyone up in Javascript.
I think I'm of the opinion that variable capture from lambda formation
should always be by value. However you can certainly make an argument
that that's inconsistent in a language which generally has
mutation/reference semantics. Whichever choice you make, though,
document it loudly I predict it will be a source of confusion.
