[Jprogramming] gl2.ijs and object constructor

[bill lam]

gl2 addon is no longer needed in j806, it is kept there for back
compatibility. If any code actually depends on it, it must be something
wrong.

I was browsing the OpenGL addon, gl2.ijs, and in the first few lines is
this:

   coclass 'jgl2'

   create=: destroy=: [:


What does this do? And what is it achieving, and why is it desired? It
seems to prevent object instantiation:

A=: '' conew 'jgl2'  NB. error

But what is the benefit of doing this? And why not just use a locale, i.e.
cocurrent 'jgl2' ?
