The message bundle that this will parse invocations of.
The definition that this will parse invocations of. Note that the exact argument type information is included in the parsing operations, but this doesn't statically determine which actual definition will be invoked.
A tuple of integers that describe how to parse an invocation of this method. The integers encode parsing instructions, many of which can be executed en masse against a piece of Avail source code for multiple potential methods. This is facilitated by the incremental construction of a message bundle tree. The instructions are produced during analysis of the method name by the MessageSplitter, which has a description of the complete instruction set.
