When env is declared in wrong way, highway will hang without indicating error.

[Siemian]

AS IS:
Declaring step like this:

bootstrap:
    default:
        - sh:
            command: "echo $VARIABLE"

instead of

bootstrap:
    default:
        - sh:
            command: "echo $(VARIABLE)"

will cause Highway to hang on:

--- Compiling the configuration file...

TO BE:
Highway should throw error

@Siemian Could you provide more information about this bug? I can't reproduce this problem. Maybe you have an Highwayfile on which problem occurred?

Unfortunately what's in issue description is all I got.

I will close this issue for now as we're not able to reproduce it anymore.
