Sorry for the clumsy description. I was trying to say that if want to do 

some_statement for some_range while some_condition;

[download]
which is perfectly legal and very useful syntax in a couple of languages I have used--including various DEC Basics which I think is where the modifier forms of if, for while & until were borrowed from-- but illegal in perl, then using 
map{ some_statement } some_range while some_condition;

[download]

is a useful substitute.

I take your point about map being conceptually different from a loop though, and I do try to avoid misusing it most of the time.

Thanks for the explaination on the traversal thing. I always forget about the special file types. I can see how that routine could disappear up it's own er...stack if it encountered a circular symlink.
