Yes, it is a bit slow here in Windows 7 too, it may become an issue in loops and such.

I've not noticed any performance issues with my version, when running it
on my Vista box at work, but on my WinXP VM at home, it does seem to
exhibit rather sluggish start up times.  That may be a consequence of
the overhead of reading the "here" documents I've used to define the
help and licence texts, every time the script is loaded; if anyone else
is observing poor performance, I could explore techniques for avoiding
that overhead.

A small suggestion: change default behavior from --nostrict to --strict.
