delimiter. It allows quoting of delimiters, and if the string has
balanced delimiters ([{<>}]) it allows nesting.
- The lexer always reads these strings into lex_stuff, except in the
- case of the operators which take *two* arguments (s/// and tr///)
- when it checks to see if lex_stuff is full (presumably with the 1st
- arg to s or tr) and if so puts the string into lex_repl.
-
+ On success, the SV with the resulting string is put into lex_stuff or,
+ if that is already non-NULL, into lex_repl. The second case occurs only
+ when parsing the RHS of the special constructs s/// and tr/// (y///).
+ For convenience, the terminating delimiter character is stuffed into
+ SvIVX of the SV.
