Where did the single-line (s) and multi-line (m) modifiers go?
The “s” (single line) and “m” (multi-line) modifiers from Perl 5 were removed in Perl 6. The “s” modifier is no longer needed since the “.” metacharacter matches anything, including a new line, all of the time. (To match anything but a newline, use “\N”). The “m” modifier is no longer needed due to changes to the “^” and “$” metacharacters and the introduction of “^^” and “$$”.
