As I understand it, since this is described in the perlop(1) man page, this operation is done at execution time, like the other operations. Thus at compilation time (where "strict subs" takes effect), it should still be a bareword. Anyway, even if the transformation is done at compilation time, there was first a bareword... > Programming Perl: 3rd Edition also has mentions it.

But "strict subs" changes the default behavior by forbidding some constructs (at compilation time). > I think it's clear that this is not a bug and is not going to change. > Feel free to take it up upstream if you disagree. As I disagree, I've reported the bug upstream: https://github.com/Perl/perl5/issues/17822 -- Vincent Lefèvre <vincent@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
