"end" in syntax cause Multiple declarations of ‘EndTransition’

[Matts966]

Thank you for developing an interesting project , and sorry for this minor edge case issue.

The syntax file below generates ‘EndTransition’ twice, so

• merging transition
  or
• forbidding "end" in syntax
  is needed.

syntax helloDSL (start) {
    simpleHello   : start -> "begin"
    helloWithName : start -> "end" name
    nameString    : name  -> "name(String)"
}

I checked the error below using haskell

[1 of 2] Compiling HelloDSL         ( HelloDSL.hs, HelloDSL.o )

HelloDSL.hs:49:1: error:
