Allow hidden terminals reference in terminal lookahead #1343

Closed gfontorbe closed 8 months ago

gfontorbe commented 8 months ago

Closes #1336

Updated the validation rule checkUsedHiddenTerminalRule to not send an error if the referenced hidden terminal is part of a lookahead.

This should also work for hidden terminal present in arbitrarily nested TerminalGroups
