That's COOL!
I'll have to look at these closer, but I definitely get what you're
doing. Thanks a million.

Last version for now, it can be improved further in various ways:
import std.typetuple: TypeTuple;
import std.metastrings: Format;
template Iota(int stop) {
static if (stop <= 0)
alias TypeTuple!() Iota;
else
alias TypeTuple!(Iota!(stop-1), stop-1) Iota;
}
enum string[]
Simpler:
import std.stdio: writeln;
import std.typetuple: TypeTuple;
template Iota(int stop) {
static if (stop <= 0)
alias TypeTuple!() Iota;
else
alias TypeTuple!(Iota!(stop-1), stop-1) Iota;
}
void foo(T, int N, int M)() {
writeln(typeid(T), " ", N, " ", M);
}
enum
This is better, probably it can be improves a bit more:
import std.stdio: writeln;
import std.metastrings: Format;
import std.typetuple: TypeTuple;
template Iota(int stop) {
static if (stop <= 0)
alias TypeTuple!() Iota;
else
alias TypeTuple!(Iota!(stop-1), stop-1) Iota;
}

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

Hi guys,
I have a 265 line program that gets a segmentation fault if I don't comment
out this while loop(I am not using delete or anything like it):
/+ while (lines.length > 0 && line.length > 3 && line[3]=='-') {
line ~= lines[0];
lines = lines[1..$];
}+/

Surely here there is no shortage of ways I can paint myself as a stupid :-)
