Implement "strict mode" where referencing an undefined variable in ${nonExistingVar} would fail

[vlsi]

Use case

Currently, a typo in variable name is hard to spot as it might silently pass to the downstream system unnoticed.

Possible solution

It might be helpful if we implement opt-in "strict mode" so referencing unknown variables becomes error rather than acceptable behavior.
