I don't see how that is even remotely relevant. I'm not allowed to write 
code that has bugs or what ? You of all people should know that I do ;-)

Nope. The *typelib data* is created when new_corridor gets constructed, 
the Spline is created only when needed, which happens when the array is 
accessed. Assigning the whole array at once instead of 
element-by-element should fix the problem. I did a quick test script, 
and it indeed seems to be the problem. (Untested) patch attached to this 
mail.

typelib/ruby should definitely allow to define constructors for data 
structures.
