Clarification around some test cases with dashes and dots

[benjreinhart]

Hello there! I'm looking for some clarification on what I believe to be a discrepancy between the tests and spec.

I was looking at the following test cases:

• dash_dash.kdl
• dot_zero.kdl

Both of these are in the input folder but not the expected_kdl folder, implying they are invalid / raise errors. However, both seem to be valid identifiers according to the spec.

node --
node .0

If I'm reading the spec right, dashes and dots seem to be valid anywhere in an identifier, including the initial character. If that's true, are these tests outdated / incorrect, or am I missing something?

Ohh, my bad, that's invalid not because of the identifier, but because identifiers cannot be arguments?
