NICE Language Committee: 2-second-message
From tynor@atlanta.twr.com Mon Jan 31 09:32:30 1994 Date: Sat, 29 Jan 94 19:29:53 EST To: bertrand@eiffel.com Subject: Creation of formals Content-Length: 973 Status: RO X-Lines: 23 Greetings, Suppiah Asokan's recent question on comp.lang.eiffel about VGCC(1) has got me to thinking about the issue of creating objects of formal generic type again. We've had similar requests from other users and had convinced ourselves that there were no implementation-related constraints that would prevent us from implementing creation of formal generic types. However, I've just reread the last 2 paragraphs on pg. 292 and I see that you explicitly deal with this restriction and explain that the limitation is due to an implementation-based constraint. I'm specifically puzzled by your mention of the need for extra fields in _instances_ of generic classes. I can't imagine what these fields would be used for. Can you enlighten me? Best regards, =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= C++: One million lemmings can't be wrong.
