Although the general convention is to use lower_case type varnames in Perl the case sensitivity of varnames can leadToProblems if you are using camel hump notation and have a case inseneitive Windows type background.
Bugs related to poorly scoped common varnames like $i, $j, $count, $timeout or often $_ can be also very difficult to isolate in my experience unless you are fortunate with the bug report.
