Moose tips
init_arg – use alternate attribute name in new()
1 2 3 4 5 | # in package Foohas qw(bar is ro init_arg quux);...# elsewheremy $foo = Foo->new( quux => 1 ); |
Foo has an attribute named “bar”, but we pass “quux” to the constructor.
See Moose::Manual::Attributes / Constructor parameters (init_arg)
init_arg – ban setting an attribute in new()
1 2 3 4 5 | # in package Foohas qw(bar is ro), init_arg => undef;...# elsewheremy $foo = Foo->new( bar => 1 ); # dies |
