This is nothing to do with fashion, it is to do with user requirements. All that is needed to make garbage collection appear in GNAT for example is some customer who really needs it and is willing to fund at least part of the development cost. We have a long list of desirable improvements for GNAT. You see a chunk of this list bitten off for each new release (each GNAT release so far has had substantial new functionality, and this will continue to be the case -- you should get to see the 3.12 list very shortly, I already posted a small preview). The prioritization of these improvements is driven partly from what we think will be generally useful, but mostly from customer requirements. Note that it is perfectly posssible to use any one of several conservative garbage collectors with GNAT. Indeed, we have delayed using virtual origins for arrays (one of the improvements on our list, which would noticeably improve efficiency, especially of Fortran type numeric codes), precisely because it would be incompatible with such collectors. Why don't these meet your needs? -----------== Posted via Deja News, The Discussion Network ==---------- http://www.dejanews.com/ Search, Read, Discuss, or Start Your Own
