exception mentioned in language spec

[PavelVozenilek]

The file language.an contains line:

arr -= 3 //Note: this will throw an exception if the array's size becomes < 0

What does it mean exception here? Application crash or something ala C++ with exception hierarchies and various levels of exception safety? This word is not mentioned anywhere else in the spec.

In debug mode (the default), this will not throw a C++ exception, rather it will fail with a single error message. The bounds are checked beforehand to do this. In release mode (the only implemented mode so far), it will just crash. Sorry for the ambiguity.
