I believe that you have correctly identified the problem.

This is documented, but obscurely. If you check in perlvar you'll find that $^I is the current value of the in-place edit. If you check in perlrun you'll find that -i calls select.

I would suggest avoiding $^I and writing the code that it saves for you. Alternately call select before setting $^I to get the currently selected filehandle, and then call select when the edit is done so that $^I and select play nice with each other.

In reply to Re^5: Make select apply to modules as well by tilly
