I think there should be test cases for literals that these seemingly strange expressions reject, which are a number with trailing _ (0x123_), and one with consecutive underscores __ (0x12__34). I like the idea of these literals. I would have found them useful on many occassions. -- Álvaro Herrera Valdivia, Chile — https://www.EnterpriseDB.com/
