nysus has asked for the wisdom of the Perl Monks concerning the following question:

I recall using a tool that told me what code in my module was requiring a higher level of Perl. For example, it would tell me the use of the // operator required version 5.10 (I believe).

I don't recall what this tool is. I just tried the perlver tool but it did not report which code was elevating the needed Perl version.

Can someone please jog my memory on what tool can tell me which code is requiring a newer version of perl? Thanks.

Re: How to determine what code is limiting needed perl version for a module

    Ah, found it with man perlver. Use the --blame option to see the limiting code.
