Yeah, I tend to agree. PHP does this terribly nastily with crap like
is_readable($file);
is_executable($file);
is_directory($file);
Bleeech! Drop the is_ , I agree:
readable($file);
executable($file);
directory($file);
In fact, I'd much rather still a more generic function like 'want' that
takes a list of things to check:
file($file); # does it exist?
file($file, 'r'); # is it readable?
file($file, 'w'); # is it writable?
file($file, 'd'); # is it a directory?
file($file, 'wd'); # is it a writable directory?
file($file, 'dw'); # same thing
Otherwise we run the risk of 200 builtins just to check file types and
modes on all the different platforms....
