How to pass reference to $self->class->method?

Question

I am calling a method as follows:

$self->class->method

I would like to pass a reference to this method as a parameter into a subroutine.

I have tried

\&{ $self->class->method }

but I get the following error:

Unable to create sub named ""

Any ideas on how to do this?

You can take a reference to static class method, but in your case you could use anonymous closure to achieve similar,

my $ref = sub { $self->class->method };

# ..
my $result = $ref->();
