Hi,

I tested on two different installations that the debugger is activating a bunch of features when using it interactively.

I suppose it's doing a use VERSION internally activating features

It's kind of surprising because I provided a -e and not a -E in the prompt.

Is this documented behavior and if not shouldn't it be?

~$ perl -de0

Enter h or 'h h' for help, or 'man perldebug' for more help.

main::(-e:1):    0
  DB<1> p $]

  DB<2> use B::Deparse

  DB<3> p B::Deparse->new->coderef2text(sub{})
{
    use feature 'current_sub', 'bitwise', 'evalbytes', 'fc', 'isa', 'm
+odule_true', 'postderef_qq', 'say', 'signatures', 'state', 'unicode_s
+trings', 'unicode_eval';
    
}
