Was it just in the range of Perl versions that I indicated?
Did it consistently happen in those ranges?
"... at least one person thought this could be a problem big enough to write some code to warn you."
I'm trying to determine why it was a "big enough" problem;
and why it was only such a problem across three Perl versions.
"... if you are using vim ..."
Thanks for the tip; however, this problem occurs in legacy $work code (probably over a decade old).
I do use vim but I didn't write this code, nor am I its maintainer.
