The \f(CW\*(C`handles_via\*(C'\fR option indicates which library of methods should be available. Valid values include Array, Blessed, Bool, Code, Counter, Enum, Hash, Number, Scalar, and String. .PP An arrayref can be provided for \f(CW\*(C`handles_via\*(C'\fR, though many of the options are conceptually contradictory. .PP .Vb 1 \& handles_via => [ \*(AqNumber\*(Aq, \*(AqScalar\*(Aq ] .Ve .SS "Moose Native Types" .IX Subsection "Moose Native Types" Although the synopsis shows Types::Standard being used for type constraints, Moose native types should also work fine. .PP .Vb 3 \& package Kitchen { \& use Moose; \& use Sub::HandlesVia; \& \& has food => ( \& is => \*(Aqro\*(Aq, \& isa => \*(AqArrayRef[Str]\*(Aq, \& handles_via => \*(AqArray\*(Aq, \& default => sub { [] }, \& handles => { \& \*(Aqadd_food\*(Aq => \*(Aqpush\*(Aq, \& \*(Aqfind_food\*(Aq => \*(Aqgrep\*(Aq, \& }, \& ); \& } .Ve .SS "True Moose Native Traits Drop-In Syntax" .IX Subsection "True Moose Native Traits Drop-In Syntax" Sub::HandlesVia will also recognize native-traits-style traits.
