Subject: [PATCH 01/12] builtin: add generic .args method
Date: Sun, 18 Oct 2020 00:56:22 +0200
Message-ID: <20201017225633.53274-2-luc.vanoostenryck@gmail.com> (raw)
In-Reply-To: <20201017225633.53274-1-luc.vanoostenryck@gmail.com>

The arity of builtin functions can be retrieved from their prototype.
So, create a generic .args method, doing the evaluation of all
arguments present in the prototype.
