=head2 method lookup
method lookup(Metamodel::MethodContainer: $obj, $name --> Method)
Returns the first matching L<method|/type/Method> object of the provided C<$name>,
by following the L<mro|/type/Metamodel::C3MRO> of C<$obj>, or C<(Mu)> if no method
object was found. Note that C<lookup> is supposed to be used for introspection,
if you're after something which can be invoked you probably want to use
L<find_method|routine/find_method> instead.
say 2.5.^lookup("sqrt").perl: # OUTPUT: «method sqrt (Rat $: *%_) ...␤»
say Str.^lookup("BUILD").perl; # OUTPUT: «submethod BUILD (Str $: :$value = "", *%_ --> Nil) ...␤»
say Int.^lookup("does-not-exist"); # OUTPUT: «(Mu)␤»
