[erlang-questions] suggestion: shorthand functions

Yes, this seems a bit harder to emulate in Erlang than my 
modest addition. :)

Note also that my primary aim is erlang for scripting, when
it's not always practical to assume the presence of 3rd 
party libraries that can be imported.

Also, again, I think that many of the functions most used in
scripts have the wrong semantics, using the {ok,Value} |
{error, Reason} approach.

BR,
