yacc/bison combined word problem

I have an if statement like the below

if false { expr }

It works, great! but i typed in 

iffalse { expr }

and it works as well :| How do i fix that? the above should be a var name not an if statement

-edit- nevermind i figured it out

In your lex file define a pattern similar to this

[a-zA-Z][a-zA-Z0-9]*

If you accidentally wrote this above the if pattern you should get an error about the pattern never being matched. Just put that pattern above and that problem will be solved
