Detailed Description

The possible values of a node in the abstract syntax tree (AST).

Constant semantic values (string literals, numeric constants, wildcard and regex patterns which are part of the mood definition) are determined during mp_init() while values which depend on the audio file (path, bitrate, etc.) are determined during mp_eval_row().

This union, and the mp_ast_node structure below are used extensively in mp.y. However, both need to be public because the lexer must be able to create AST nodes for the constant semantic values.
