There is no practical difference between the values of '1' and 1. You could possibly dig into the guts of SVs and test whether your variable has been used as a number/string yet, but that would be a lot of work for questionable gains.

The real (XY problem) question is; why do you care? Perl will give you a string where appropriate (concatenation operation, say), and a number where appropriate (eg: addition operation)
