I'm not sure exactly what you're going for, but maybe this helps …
Thanks. It looks like I was thrown off by
Data::Dumper not dereferencing the subroutine references and instead returning something weird, and also the general need to dereference the subroutine references in other code. Other than that, my idea seems to have been spot-on.
Update 2: The syntax &{(MODES)[0]} also works, and you may consider it more elegant …
I would, yes.
However, this example snippet will return a syntax error (
near ")["):
my $tmp = 42 + (&((MODES)[1])())[1];
The same goes for:
my $tmp = 42 + (&((MODES)[1]))[1];
Luckily, it can be worked around using:
my $tmp_ref = (MODES)[1];
my $tmp = 42 + (&$tmp_ref())[1];
I don't quite understand why the interpreter trips, but since it's easy to work around it using a temporary variable, I wanted to leave that here for reference as well.
