Maybe. Have you tested this with every significant code path in the Perl interpreter on multiple platforms? Do you even know the significant code paths? Can you guarantee it will remain stable with tied variables? XS subs? Refs? Resized arrays? There are a lot of permutations you would need to go through before I'd be convinced this array modification "works fine".
I think the documentation is pretty clear: "don't do that". Just because the implementation happens to (seem to) work for whatever case you've come up with, directly going against the documented limitations of a fundamental Perl loop keyword is just begging for trouble, either now, or (possibly with greater consequences), later on down the road when everyone has forgotten the stupid unnecessary risk you took, with a for loop or two buried in a large program.
What's wrong with
Sorry if this seems a bit doom and gloom, but I really just don't get what you hope to gain, here. Perhaps you could explain?
