Course of Raku / Regexes and grammars / Grammars
The parse tree, make and made
Parsing tells you that a string matches a grammar, and it builds a
parse tree — a match object with a named capture for every
token. But usually you do not want the raw text; you want a
result: the integer 42, not the characters
4 and 2.
This section shows how to walk the parse tree, and how to attach a
computed value to a match with make, then read it back with
made.
