ARG double evaluation

[ohhmm]

When evaluated ARG contains another ARG reference it expected to be fully expanded.
Example line: https:/ohhmm/openmind/blob/e7e9170d4ebb86e32112ae0b4397db51925478f6/.devcontainer/Dockerfile#L4

ARG LLVM_MAJOR_VERSION=17
ARG LLVM_FULL_VERSION=$LLVM_MAJOR_VERSION.0.6

Hovering LLVM_FULL_VERSION hints $LLVM_MAJOR_VERSION.0.6 but 17.0.6 is expected.

@rcjsuen, what are your thoughts on supporting this?

Very interesting use case. @ohhmm I guess it knows that the . is a word separator? If you use _ I presume Docker won't interpret things quite the same way?
