Template instantiation | ! | Top-level ',' in rhs expression treated specially. Cannot be chained |
14.5 | Lambda abstraction | => | Not a real operator, occurs twice, this is binding power to the left. |
14 | Postfix operators | . ++ -- ( [ | ( and [ treat top-level ',' in rhs expression specially and require balanced ) or ] in order to be completed |
13 | Power operator | ^^ | Right-associative |
12 | Unary operators | & ++ -- * + - ! ~ cast | |
