I've been looking at migrating a reasonably large ship motion
library (tens of thousands of lines) from C# to D. I've become
quite enthusiastic about D, and most of my problems have been
relatively minor (e.g., inconsistent bugs with
std.container.Array, would like orange serialization to give me
an error telling me I didn't register a class before calling
serialize). I suggest that the language require ref and out
when calling functions, as C# requires. This would make code
easier to understand, and would also eliminate the problem I
had when the wrong function from the following choices was
mistakenly called:
parseLineInts(string text, int positionStart, out int j0, out
int j1)
parseLineInts(string text, out int j0, out int j1, out int j2)
I note that the second function calls another function as
follows:
int positionStart = 1;
parseLineInts(text, positionStart, j0, j1, j2);
I look forward to seeing feedback from D experts. This is the
only significant change that I could think of recommending for
the language.
+1. The fact that a value type is modified should be information
the programmer can see at a glance.

Citation? I'm using C# 5.0 with Visual Studios 2012 on Windows 8
right now and ref/out are still required at the call sight of
functions.
