All in all, probably a good thing.

Take the base class and split out the validation:
my $result= eval { $obj->execute_foo(@stuff) }
or die "Unhandled exception in Foo: $@";
package Foo;
sub validate_foo
{
...
die "Bogus valiate foo: bar is not given" unless $argz->{bar};
...
}
sub execute_foo
{
$_->[0]->validate_foo;
...
}
package MoreFoo;
use base qw( Foo );
sub execute_foo
{
$_->[0]->validate_foo;
...
}
