Yes, but I had this little problem and suddenly realised that the mysterious 
``(abc) {cmd...}
actually might be used for something! I have never used it before.

OK. Would you consider making ``(abc)
a parse time error? only allow ifs=asd, or ifs=( a s d ), not ifs=(asd) too.
Or, as with the confusing

if ( {}  && {} ) {cmd...}
vs
if ( () && () ) {cmd...} 

document it.

split a filename into directory, filename and suffix. the suffix should be allowed to have more than 1 character.
the idea is to make the previously emailed base_name function (made by Carlo Strozzi <carlos@linux.it>)
more like the os utility basename.
