Nikita Popov a2443aaefa Make check in numeric literal separator emulator more precise ... a) Don't check for !== false, preg_match() return 0 if there is no match. This effectively means that the check was always true. b) Check for hex characters only if there's an 0x prefix. 1_1 is very likely a numeric separator, but a_b might well be part of an identifier.
