Yes, there is one. It is a problem that the Perl4-ish package separator
causes in Perl 5 already. One that bites many coders:
"Eat at $joe's"
means in Perl 5:
"Eat at $joe::s"
would mean in Perl 6 if we used the ' for hash subscripts:
"Eat at $joe{'s'}"
Apostrophes are needed in text. Many languages use them to mark the
absence of some letters. I don't know of any such use of the backtick,
except by people new to computers who use them as if they are
apostrophes :)
I dislike the attempt at getting balanced quotes in ASCII that involves
` and ', but it shouldn't be a problem as that in normal use always
follows whitespace or at least interpunction.
