I still think a cleaner solution in this particular case is to have a different operator for string concatenation. Then "4".3 is unambiguously "43", and "4" + 3 is unambiguously 7 :-)
Remembering lists of default behaviour: this reflects a difference in the intended audiences for Perl and Python. Perl's really intended for people who use it every day, and so don't have to look up this stuff.
