I'll ignore the fact that binding the arguments to magic,
predefined names has the elegance of a fart interrupting a solemn
moment. The larger problem is the type of _argptr.
That surprises me. Your string mixin callbacks (or whatever is the
correct name for this idiom) in std.algorithm also use magic,
predefined names like "a".
The situations are different. (The "$" in array index is also
different.)
How are the situations different?
I don't have much time to explain, but the code in which a and b are
used (which is restricted to an expression) cannot possibly define its
own symbols called a and b. Also, user code can never define $. In
contrast, _arguments is a valid, nonreserved D symbol that's just up for
grabs.
K. Then rename _arguments to $arguments. Problem solved.
