tf12 errors on parameter list format

[twellspring]

For the tf12 parser the block syntax works as expected:

  parameter {
        name  = "tls"
        value = "enabled"
      }
  parameter  {
        name = "audit_logs"
        value = "enabled"
      }

But the list of objects returns a warning/failure condition for the same rule

  parameter   = 
    [{
        name  = "tls"
        value = "enabled"
      },
      {
        name = "audit_logs"
        value = "enabled"
      }]

Per https://www.terraform.io/docs/configuration/attr-as-blocks.html this syntax is not recommended, but is still supported.

Assertion that works for blocks and fails for list of objects

    assertions:
      - some:
          key: parameter
          expressions:
            - and:
              - key: name
                op: eq
                value: tls
              - key: value
                op: eq
                value: enabled

I am able to reproduce the error and am working on a resolution. So far, looks like separate blocks are grouped together as a single block and then linted. Whereas a joined block that's already in that format isnt read correctly, and instead UNDEFINED is returned. Looking into why now.

In this example, fail_best has the working, separated block syntax and fail_alt has the failing, joined as a list block syntax.
