However, there are situations that require reverting to no stricter, perhaps more often than you think.

Sure, I hate MixedCase identifiers, but in some shops that's the requirement. (I prefer Mixed_Case over MixedCase, but I want Mixed_Case to mean something special, more than lower_case, but perhaps less emphatically than UPPER_CASE.)

C-style for loops are concise when dealing with complicated indexing, though granted they are just compact syntax for while loops, if more emphatic-looking.

I'll grant unless is not very appealing, but is lazy. However, I like until, because it's often paired up as in do {...} until (). But I suppose it's equivalence with while (not(...)) is what's got everyone agitated.

I think we should tread carefully, so that Perl doesn't suffer more from the shortcomings of Lisp or Pascal (as in "There might be one way to do it in Pascal).

In the end, we'll all have to make our own choices (except those who get their choices handed to them ;)
