Is D painted into a corner?

[Brother Bill]

It seems like 'templates' are the 'Achilles heel' of D.

Without starting a flame war, has D gotten to the point where 
ordinary mortals have difficulty coding in D with 'templates' 
such as 'cycle' requiring rewrites into 'myCycle'?

Does D now require 'deep' memory into layers of history and 
workarounds?

Is D a general purpose language, suitable for Application 
Programming, or does it have a more limited scope?
