Not a complete polyfill, since $newfunc is a closure and not a string,

relies on the lambda itself being a string though.
This has impact on a few things, i.e. Reflection or users might guess
the name. Anyways: Take away: A polyfill won't be 100% identical.
However the typical use case should be around usort() or similar where
this doesn't matter.

I'm not entirely sure about what you mean. On my system, create_function
returns something like '\x00lambda_1'. Do you mean that users are
guessing such a string in order to use it? Sounds like the smelliest of
code smells.
