I also don't have any problem with tools, what matters is what
the customer wants and with what I can make him happy, not what
the tool flavor of the month is.
Personally, even thought it might come differently in my posts, I
also believe there are situations where MMM is much better than
GC. Or where GC is not even feasible.
The thing is, regardless of what anyone might think, the major
desktop OS are integrating reference counting and GC at the
kernel level. Now when the systems programming languages that are
part of these OS, offer these types of memory management, there
is no way to choose otherwise, even if one so wishes.
