// int isn't a reserved word, right?
// So this should work fine!
int = 7;
// Let's try using it!
Wait, what? A parse error? Why, you might ask? (int) is a special case in the
lexer. Turns out that casts are lexed specially. Why? Probably to stop the type
names being reserved words... that worked out spectacularly, didn't it? The
best bit, though, is that this has been around since PHP 3, so it's most likely
the fault of Zeev Suraski or Andi Gutmans. Good job.
