streq() is something I woudn't mind.

I've too often confused !strcmp(a,b) as "!streq()" which is not the
case. Which is why I always use strcmp(a,b) == 0, which to me I see the
'==' as eq. I also consider strcmp(a,b) != 0 as not equal. Again, the
mind that sees "==" and "!=" can just translate that to human language.
Where !strcmp() is just gibberish ;)
