digitalmars.D.learn - Is it std.regex, or is it me.

Given the following, where X and Y mark the spot:

	X epochRegex =3D regex("([0-9])+:");
	Y aEpochCapture =3D matchFirst(aVersionString, epochRegex);
	Y bEpochCapture =3D matchFirst(bVersionString, epochRegex);

If X or Y are const or immutable the code fails to compile. Only if
both X and Y are auto does this code compile. So question to the
audience: how do you do single assignment programming in D? Is it, in
fact, impossible to program with bindings rather than variables in D?

And yes this does seem to be a violation of the Principle of Least

naturally const even if you opened it for reading.
