D vs. ISRs (interrupt service routines) or Which D language features implictly allocate memory?

[Sean Kelly]

As others have said, string concatenation (via ~), the .dup property, 
insertions into AAs (and possibly removals as well), and 'new' calls. 
Those are the only language features I can think of that allocate.  As 
for library calls, Tango almost never allocates internally.  This has 
actually been a source of contention for some, but I think the benefit 
is worthwhile.
