parser descends all includes before parsing any code

[Telcrome]

Consider two files:

symboldefinition.gpp:
symbol domain Animals = { TIGER, ELEPHANT }

main.gpp:

#include "symboldefinition.gpp"

action feed_animal(symbol animal) {
  domain animal in Animal // <<<< problematic with outside defined domains
  [...]
}

Will add a tested example and edit the issue next tuesday. Also the output might be interesting, because the error message did not immediately help us find the problem.
