James Bardin d060a3d0e8 eval variables with unknown expansion data
While we don't have any expansion info during validation, we can try to
evaluate variable expressions to catch some basic errors. Do this by
creating module instance RepetitionData with unknown values. This
unfortunately will still miss the incorrect usage of count/each values,
but that would require the module call's each mode, which is not
available at this time.
