Warnings when using Mojo::Util standalone

[e477]

I like using Mojo::Util as a convenient set of tools outside of Mojolicious projects, too. Since commit 413320b released with 6.04 I get the following warnings when trying to do so:

Useless use of a constant ("has") in void context at /usr/share/perl5/vendor_perl/Mojo/Base.pm line 39.
Useless use of reference constructor in void context at /usr/share/perl5/vendor_perl/Mojo/Base.pm line 39.
Useless use of private variable in void context at /usr/share/perl5/vendor_perl/Mojo/Base.pm line 65.
Useless use of reference constructor in void context at /usr/share/perl5/vendor_perl/Mojo/Base.pm line 65.
Useless use of private variable in void context at /usr/share/perl5/vendor_perl/Mojo/Base.pm line 73.
Useless use of reference constructor in void context at /usr/share/perl5/vendor_perl/Mojo/Base.pm line 73.
Useless use of private variable in void context at /usr/share/perl5/vendor_perl/Mojo/Base.pm line 77.
Useless use of reference constructor in void context at /usr/share/perl5/vendor_perl/Mojo/Base.pm line 77.

Thanks, fixed. I'm not happy with the solution though, and might just revert the original optimization instead. 5adf558

02:16 @mst sri: isn't that just a circular require problem?
02:16 @mst yep
02:16 @sri possibly, the warnings are very useless though
02:21 @sri curious how "Mojo::Util::monkey_patch $caller, 'has', sub {
attr($caller, @_) };" causes "Useless use of a constant ("has") in
void context at lib/Mojo/Base.pm line 39."
02:21 @sri i guess Mojo::Util::monkey_patch is not yet defined
02:21 @sri triggering that oddity
02:21 @mst and so you parse it as indirect object notation
02:21 @mst $caller->Mojo::Util::monkey_patch(), 'has', ...
02:21 @sri oh shit... of course... indirect object notation
02:22 @sri facepalm
02:22 @mst which is what ciruclar requires cause, which can easily break
things later, which is why I went "ew" at this
02:22 @mst Moose::Util::TypeConstraints predeclares its subs for exactly this
reason
02:22 @sri i guess i can predeclare monkey_patch
02:23 @mst right
02:23 @mst sub monkey_patch;
02:23 @mst sorts it out

Will this solve the following problem too?

use Mojo::Util;
use Mojo::UserAgent;

results in "syntax error at [...]/Mojo/IOLoop/Client.pm line 30, near "has reactor".

@Tekki Yes.
