# This implements call logic, which is simply like a c call (not send, that involves lookup and all sorts)

|
#
|
||
|
# The only target for a call is a MethodDefinition, so we just need to get the address for the code
|
||
|
# and call it.
|
||
|
#
|
||
|
# The only slight snag is that we would need to assemble before getting the address, but to assemble
|
||
|
# we'd have to have finished compiling. So we need a reference.
