When a function signature looks like this

if (isInputRange!RoR && isInputRange!(Unqual!(ElementType!RoR))

== Unqual!(ElementType!R)))
or like this:
E[] replaceFirst(E, R1, R2)(E[] subject, R1 from, R2 to)
if (isDynamicArray!(E[]) && isForwardRange!R1 &&
is(typeof(appender!(E[])().put(from[0..1]))) &&
isForwardRange!R2 &&
is(typeof(appender!(E[])().put(to[0..1]))));
it's understandable why documentation is mandatory.
That's true, Rumbu!
And despite that, it's always marvel me the fact that I can
simply read the above and actually "understand it"!
It's some kind of magic, but maybe it's simply why I'm forced to
read too much C++ recently... :-P
PS ... the most difficult part for a beginner maybe is the
historical "is(typeof( ... bla bla ...)"
