>You could imagine a more clever implementation of lexical environments that avoids this problem. Each closure could have a dictionary containing only the variables which it actually reads and writes; the values in that dictionary would themselves be mutable cells that could be shared among the lexical environments of multiple closures. That is basically how Lua implements closures. https://bugzilla.mozilla.org/show_bug.cgi?id=542074 |
