%switch% can be cumbersome: lexer->lookahead['type']) { case Lexer::T_SELECT: $statement = $this->SelectStatement(); break; case Lexer::T_UPDATE: $statement = $this->UpdateStatement(); break; case Lexer::T_DELETE: $statement = $this->DeleteStatement(); break; default: $this->syntaxError('SELECT, UPDATE or DELETE'); break; } ]]>

%match% improves this: lexer->lookahead['type']) { Lexer::T_SELECT => $this->SelectStatement(), Lexer::T_UPDATE => $this->UpdateStatement(), Lexer::T_DELETE => $this->DeleteStatement(), default => $this->syntaxError('SELECT, UPDATE or DELETE'), };]]>

Differences with %switch%: It is an expression, so returns a value %match% does not do type-juggling No automatic fall through Exception if nothing matched
