I think this thread is not TOO old to use as a place to beg for
help :)
I've wandered into this nightmare, and I'm hoping someone who's
been down this road can point the way back to the light.
Summary: "no OPENSSL_Applink" runtime error when executing D
openssl application.

Do you mean just the number of dimensions, or do you mean the size
along each dimension? Knowing just the # of

It's certainly better. I'll have to look at how this plays with some
of my other usage, where dimensions come into p
I have the following sample program:
---
import std.algorithm, std.stdio;
real mean(T: Elem[], Elem)(T data) {
return reduce!("a + b")(0.0, data) / data.length;
}
real mean(T: Elem[][], Elem)(T data) {
real partSum = 0;
int count = 0;
foreach (row; data)
{
partSum += reduce!
I'm just trying to figure out what the error would be, exactly. That a
programmer, knowing the language specification, obeyed it and wrote an
expression using the shortest syntax?
Rhetoric aside, the result is not unambiguous, it just requires that the
reader understand precedence. That's an arg

That gets less true as the cost of a try block goes up. Even if logic

This seems to be an increasingly common but still expensive suggestion
for error handling. Unless D has made great strides in exception

std.string has a repeat() function. Try:
import std.string;
void main()
{
string divider = repeat("-", 5);
writeln(divider);
}

Whatever confidence you inspired by
@bearophile:
Got it. Had it mostly worked out before reading, but this helps clarify
the static foreach part.
Thanks, gang!

Ok, I've gone over this, adapted it, and mostly understand it. I just
have one question left:

In writing templates that make heavy use of alias parameters, does
anyone else feel uneasy about whether the caller will pass a type, a
value, or a schmoo? I'm having a hard time getting my head around
how wide-open aliases are and trying to resist the urge to put in
thousands of static asserts to
That's COOL!
I'll have to look at these closer, but I definitely get what you're
doing. Thanks a million.

Thanks for all the suggestions!

Forgot a couple of things:
- this is all using D2.047.
- Another question (in reference to part 2 before): I'd like to
support about 4 base types and 5 or 6 different matrix sizes. So
that's roughly 20 type combinations for my template. But I decide
these based on command-line arguments at run
I'm working on a program to do statistics on matrices of different sizes, and
I've run into a handful of situations where I just can't seem to find the
trick I need. In general, I'm trying to make my functions work on static
arrays of the proper size, and template that up for the different sizes I
20 matches
