It's that mentioning them twice that bother's me, since it's (a bit) error prone - due to copy and paste, a longer (or shorter) my (var1, var2, ...) list will not neccessarily be detected at once. Having had the possibility to localize them via
eval, each and only each valid named parameter would have been declared and initialized correctly. Later mispellings of these variable names would be detected via use strict.
Besides, now I ALSO got the feeling I should have looked at Params::Validate!
;-)
I find it hard to get an decent overview over the CPAN modules, thus gave up at some point and probably reinvent the weel again and again...
Thank you for your support!
