Re^4: Why is Dumper returning "!!1" for true file test?

Are you referring to builtin::true etc. in builtin? Nobody has mentioned them yet in this thread.

Or are you talking about the internal &PL_sv_yes ?

On a side note: shouldn't it be possible to activate true and false while silencing the warnings with just one pragma?

  
use experimental qw/builtin/;
use builtin qw/true false/;
use Data::Dump;

ddx $];
dd [true,false]

Them, Perl's booleans = `&PL_sv_yes` and `&PL_sv_no`. Recently introduced functions = `builtin::true` and `builtin::false`	[reply] [d/l] [select]
