good reasons not to use D?

[Laeeth Isharc via Digitalmars-d-learn]

I'm writing a talk for codemesh on the use of D in finance.

I want to start by addressing the good reasons not to use D.  (We 
all know what the bad ones are).  I don't want to get into a 
discussion here on them, but just wanted to make sure I cover 
them so I represent the state of affairs correctly.

So far what comes to mind: heavy GUI stuff (so far user interface 
code is not what it could be); cases where you want to write 
quick one-off scripts that need to use a bunch of different 
libraries not yet available in D and where it doesn't make sense 
to wrap or port them; where you have a lot of code in another 
language (especially non C, non Python) and defining an interface 
is not so easy; where you have many inexperienced programmers and 
they need to be productive very quickly.

Any other thoughts?
