I actually think that's pretty cool, despite my desire to see a native switch. I have often use hash constructs to accomplish switch-like behavior, and I think that the for ( $var ) ... approach is much nicer...
# Example of the hash-construct "switch", which is limited and has no
+"default".
# The output of this code is "abc"
use Moo;
my $val = 'c';
my @args = qw( abc );
my $obj = __PACKAGE__->new();
{ a => sub { say 'a' },
b => \&b,
c => sub { $obj->c( @_ ) },
}->{ $val }->( @args );
sub b { say 'b' };
sub c { shift; say for @_ };

A mistake can be valuable or costly, depending on how faithfully you pursue correction
