The Perl parser could confuse the bareword shift in the braces with its core function shift instead of converting it to a string.

I'm pretty sure that Perl will always take $hash{shift} to mean the hash key "shift", although adding any other characters will change that ($hash{+shift}, $hash{shift()}, etc.) See also.
