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.

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