The example is quite special.  It allows to append an extension, but
it disallows to remove one.

What I do very often in bash is

     for file in *.ps ; do
     	 convert $file ${file%%ps}pdf
     done

Maybe your syntax can be extended, for instance like this:

      convert {} {/ps$//}pdf
or 
      convert {} {/ps$/pdf/}

Using regexps is much more powerful than the substring approach in
bash anyway.
