Sorry - I wrote this in a hurry, and I should have said on my 
experience of using D in finance (not the whole sector, which is 
absolutely enormous and very diverse), and what lessons and 
general things might be useful for others considering D.

I can imagine lack of fixed point might be a problem.  Shouldn't 
this be in Phobos?  If BigInt is, then why not fixed point?  
There is this library here - had some problems compiling it last 
time (dmd versions), but it seems at least somewhat 
thought-through:

Not sure if I replied to the suggestion that D isn't suitable for 
enterprise use.  That's a word with a nice penumbra of 
connotations.  If you mean you shouldn't use it for a project in 
a multinational where thare are 100 people working on it and 
without extensive experience of using D by the key people 
already, then sure.  If you mean that D isn't suitable for 
serious work where there are very large amounts of money at 
stake, and the organisation may be a decent size then I strongly 
disagree.  The examples of Facebook's worp, Sociomantic, EMSI, 
and the German guys who do the Norwegian train system ought to be 
sufficient to make that point...
