What is it?

Well, the lexer supports floating points but it somehow supports this:

module simple_literals;

int var = 1.2.2;

However, it actually returns 1.2, it's just that the lexer should actually hand up on something like this.

Mmmnh....

It sees this:

.2 at (3, 11), . at (3, 14), 2

Actually, I see it sees 1.2.2 as 1.2 (float . (dot operator) followed by literal 2. this is fine.

Infact we see this work even with 1.2.2.2 which is (1.2) . (2.2):

module simple_literals;

int var = 1.2.2.2;

This is fine ✅ :

[module at (1, 1), simple_literals at (1, 9), ; at (1, 23), int at (3, 1), var at (3, 5), = at (3, 9), 1.2 at (3, 11), . at (3, 14), 2.2 at (3, 15), ; at (3, 18)]

Actually, I see it sees `1.2.2` as `1.2` (float `.` (dot operator) followed by literal `2`. this is fine. Infact we see this work even with `1.2.2.2` which is `(1.2) . (2.2)`: ```d module simple_literals; int var = 1.2.2.2; ``` This is fine ✅ : ``` [module at (1, 1), simple_literals at (1, 9), ; at (1, 23), int at (3, 1), var at (3, 5), = at (3, 9), 1.2 at (3, 11), . at (3, 14), 2.2 at (3, 15), ; at (3, 18)] ```
