Why aren't you using D at work?

We develop tailor made CRM/ERP solutions, mostly in C# or ASP.net.

On the client side, it's obvious why I can't convince anyone to 
use D (lack of standard GUI, lack of i18n support, unavailability 
on WinRT/iOS/Android)

On the server side, vibe.d cannot compete with asp.net 
(AD/SQL/Sharepoint/Office integration, Razor syntax, IDE 
integration, report generation).

Therefore I took advantage of a situation we encountered - 
payroll calculation for a big client (>50000 payrolls) took more 
than 6 hours to complete. So I tried to write some payroll 
calculation components in D. The main problems encountered were:
- lack of a decimal data type - you cannot perform monetary 
calculation using floating point.
- lack of a chinese or japanese calendar in the std.datetime 
module;
- missing of overflow checks for integral data types;
