Fixes #94
The
terraform_unused_declarations
rule recognizes unused variables by walking through all expressions and seeing if a variable reference exists. However, this way cannot recognize which block is being walked, so false negatives like #94 may occur.This PR changes the rule so that if an expression reference is inside a variable validation block, it will not be marked as used.
