# A dynamic call calls a method at runtime. This off course implies that we don't know the
# method at compile time and so must "find" it. Resolving, or finding the method, is a
# a seperate step though, and here we assume that we know this Method instance.
#
# Both (to be called) Method instance and the type of receiver are stored as
# variables here. The type is used to check before calling.
#
# Setting up the method is not part of the instructions scope. That setup
# includes the type check and any necccessay method resolution.
# See vool send statement
