Bug 12813 – Parser is confused between float and UFC syntax

According to the docs (lex) """ Floating literals can have embedded ‘_’ characters, which are ignored. The embedded ‘_’ are useful for formatting long literals to make them more readable, such as using them as a thousands separator """ And the following examples are given as valid. 123_456.567_8 // 123456.5678 1_2_3_4_5_6_._5_6_7_8 // 123456.5678 1_2_3_4_5_6_._5e-6_ // 123456.5e-6 However: 123_456.567_8 // OK 1_2_3_4_5_6_._5_6_7_8 // ERROR no property '_5_6_7_8' for type 'int' 1_2_3_4_5_6_._5e-6_ // ERROR no property '_5e' for type 'int' Marking as regression because this would have been fine before UFCs.

So you've updated the grammar page, but you haven't updated/removed the erroneous examples on the lex page?
