should be 'has $.age is rw'. The "is" indicates a trait (not an
assignment).

Etiher method a needs to be inside class foo, or it needs to be a
subroutine, and refer to foo instead of self here.
A method outside a class doesn't ususally make sense, which is why you
get this message:
Other potential difficulties:
Useless declaration of a has-scoped method in mainline (did you mean
'my method a'?)

the indirect method call syntax is the right approach, you just got too
many other details wrong to make it work.
