The point is not to pollute module namespace with implementation details
that are only relevant to that one function.

Also, if you're worried about inlining, use LDC instead of DMD. LDC is
well able to inline nested functions.  Don't make judgments based on the
DMD backend; it's well-known that its optimizer is ... sub-optimal...

The point is not to pollute module namespace with functions that are
only relevant as implementation details of one function.
