Add Tapioca compiler

I forgot this initially - can we generate a signature for perform as well? It'll be the same type signature as perform_now, but an instance method, instead of a class method.

Do you need to copy this complex method over? I would have instead done a call to compile_method_parameters_to_rbi and then walked over the result to find all required params of type T::Types:FixedHash and replace them with the keyword parameters instead.

[st0012]

I want to do that too but AFAICT the T::Types information is not captured in the rbi types:

<RBI::TypedParam param=#<RBI::ReqParam:0x000000013295e420 @comments=[], @loc=nil, @name="params", @parent_tree=nil> type="{shop_id: ::Integer, resource_types: T::Array[::ResourceType], locale: ::Locale, metadata: T.nilable(::String)}">

Right, but you can always match that data with method_types = parameters_types_from_signature(method_def, signature) to find all required params of that type.

[paracycle]

Ah, sorry, those are also strings. I guess you could do:

signature = signature_of(method_def)
fixed_hash_args = signature.arg_types.select { |arg_type| arg_type[1].is_?(T::Types::FixedHash) }

and loop over those to match the params to the ones you need to replace.
