No I don't. Perl will treat each scalar either as numeric if it has a valid numeric value, or otherwise as a string. It is either a string or not a string. This leads to variables being manipulated numerically if they have ever been numeric and that value survives, and otherwise as strings. It is intuitively what you would expect.
