Hi,
I wondered if it would be useful/good/nice if the syntax for
specifying role parameters would be the same as the standard
subroutine signature syntax (minus the colon, which
separates the parameters which do account to the long name
of the role from the ones which don't).
E.g.:
role MyRole[
Str $required_param,
Bool ?$optional_param_defaulting_to_undef,
: # beginning of the parameters which don't account to the
# long name of the role
Num ?$opt_param_defaulting_to_42 = 42,
Any ?$evil_var = $CALLER::_,
] {...}
$x does MyRole["abc", 1];
# or
$x does MyRole[required_param => "bar", evil_var => 23];
# etc.
