This is my "shortcut"...

a = (isset(a{0}) ? a : b;

My *very* unscientific testes show that this is somewhat faster
than...

a = (isset(a) ? a : b;

It just looks for the first character, or first elements of an array
opposed to the entire variable.

I'm not surpised it's faster since

a = (isset(a) ? a : b;

won't work!

This is no PHP. And what are the curly braces doing there?

I really doubt that there's a difference in performance, at least not
one that matters at all.
