That's a very good idea. I'm a huge fan of printf-debugging (comes from
years of developing on platforms that didn't have a good
readily-available
debugger), so not being able to do that in pure functions would be a very
critical roadblock for me for using purity. In fact, it's already been a
royal PITA for CTFE.
Same for me. I'm a fan of printf debugging not because of lack of
debuggers, rather because of their "heaviness" & lack of flexibility.
Debug output is by me far more direct, quicker & lighter; and agile.

I'm not a day-to-day D programmer but it's seemed to me for a while that
having a print/log function that would work in normal code, in pure code
and in CTFE would be extremely useful.
