I think it's horribly Perl-like, but I'll reserve judgement until you 
tell us exactly what you expect this to achieve.  So far you appear to 
be trying to create random operators to no great purpose.  What is the 
problem you are seeking to solve here, and why is it worse than the 
problems you are creating?
