Hi,
You should try LISP-like languages : if you want to add an "unless" fom and
whatever form you like, you just can do it...
But the basic Lisp (or Scheme) has very few special forms, so that it can be
easily interpreted or compiled.
The trouble with rich languages as Perl is that the compiler has to know all
those synonyms and it get more complex for only little benefit.
And somebody who learns it might be confused with all those different
syntaxes.
