So there you have it

But you say it doesnt have the use statement, well then 

$ perl -le " use B::Deparse; use 5.014; print B::Deparse->new->coderef
+2text(sub{ use 5.014; }) "
{
    use strict;
    no feature;
    use feature ':5.12';

}

Oh noes its the same thing ... luckily O 

$ perl -MO=Deparse -le " use 5.014; "
BEGIN { $/ = "\n"; $\ = "\n"; }
sub BEGIN {
    require 5.014;
}
-e syntax OK

But you say you have to look inside sub O::import ....

Like I said earlier :) extend use feature to support turning-on-and-documenting all these features ... but I don't see introspection as a necessary part of that api , Deparse can take care of that

Good luck
