Hi,
Thanks for all your suggestions .. unfortunatly last time I used
the profiler it crashed, but I'll take another look.
It seems that there is no real gain to be made by stripping out
the signatures - I suppose if there was, perl would do an equivalent
optimization.
I'll keep an eye out for caching opportunities in the code.
I keep forgetting what Donald Knuth once wrote, "premature
optimization is the root of all evil." ....
