Implement the hash pattern matching interface for ParseResult.
Walk the tree and mark nodes that are on a new line, loosely emulating the behavior of CRuby’s ‘:line` tracepoint event.
Implement the hash pattern matching interface for LexResult.
Implement the hash pattern matching interface for ParseLexResult.
Implement the hash pattern matching interface for Token.
Visits each node in ‘nodes` by calling `accept` on each one.
GNU Readline watis for “keyseq-timeout” milliseconds when the input is ambiguous whether it is matching or matched. If the next character does not arrive within the specified timeout, input is considered as matched. ‘ESC` is ambiguous because it can be a standalone ESC (matched) or part of `ESC char` or part of CSI sequence (matching).
ed-insert (vi input: almost all; emacs: printable characters) In insert mode, insert the input character left of the cursor position. In replace mode, overwrite the character at the cursor and move the cursor to the right by one character position. Accept an argument to do this repeatedly. It is an error if the input character is the NUL character (Ctrl-@). Failure to enlarge the edit buffer also results in an error.
ed-digit (emacs: 0 to 9) If in argument input mode, append the input digit to the argument being read. Otherwise, call ed-insert. It is an error if the input character is not a digit or if the existing argument is already greater than a million.

self-insert (a, b, A, 1, !, …) Insert yourself.
