The Many Faces of D - slides

>I continue to be intrigued by people who believe that code, unlike text, is more readable in a monospace font.  Personally I think monospace fonts make code unreadable,<

I guess it's a matter of personal preferences. But non-proportional fonts have two advantages: 
- it's easy to count spaces, vertical alignments and so on;
- often if the non-proportional is well designed it's simpler to tell apart glyphs like Jl1j0oO;:.

Both DMD and LDC (and probably GDC too) currently are able to turn some cases of tail recursion to iterative code.

Since many years and many versions of Python the pythonic way to write that is to use a lazy iterable:

    def sumOfSquares (sequence):
        return sum(item * item for item in sequence)


I have suggested few times a list/lazy comp syntax for D too, and I have tried to explain why it's a good thing (it helps "chunking" in the mind of the programmer).
