yaml highlighting/textmate recognises some integers as strings (or vice versa?)

[pedroterzero]

Some integers (or strings?) are treated differently even though they look the same to me.

In each comment I've specified what the scope inspector reports the scope as.

Testcase:

test:
  - test: 01 # constant.numeric.integer.yaml
  - test: 02 # constant.numeric.integer.yaml
  - test: 03 # constant.numeric.integer.yaml
  - test: 04 # constant.numeric.integer.yaml
  - test: 05 # constant.numeric.integer.yaml
  - test: 06 # constant.numeric.integer.yaml
  - test: 07 # constant.numeric.integer.yaml
  - test: 08 # string.unquoted.plain.out.yaml
  - test: 09 # string.unquoted.plain.out.yaml
  - test: 10 # constant.numeric.integer.yaml

This is what it ends up looking like for me:

I'd expect them all to be the same; so either they should all be integers or they should all be unquoted strings. Right?

The check for base 10 numbers does not allow for prefixing 0's
[-+]? (?: 0|[1-9][0-9_]*) # (base 10)

cases 00 - 07 are handled by the base 8 regex
[-+]? 0 [0-7_]+ # (base 8)
which can also handle infinite prefixed 0's
