import std.regexp;
int main () {
    char[] foo = "foo = bar";
    int i = std.regexp.find(foo, "[^\\]#");
    return 0;
}
---

This outputs "Error: invalid range". According to the documentation, this should return -1, since the input does not contain an octalthorpe (#) that is not preceded by a backslash.

Adding an octalthorpe doesn't help matters; it produces the same error. Also, adding the attribute argument doesn't help.

With an example this small, I think this is probably a bug, but I'd like to check here before submitting a report -- am I doing something wrong?

Argh -- forget that. I forget that regexps require an extra level of escaping; that should have been:
---
std.regexp.find(foo, "[^\\\\]#");
---

This is why I ask now rather than submitting bug reports first.

Thanks!

If you use WYSIWYG strings, you can avoig the ugly double escaping:

std.regexp.find(foo, r"[^\\]#");

or

std.regexp.find(foo, `[^\\]#`);

I've also never heard of a pound sign being called an "octalthorpe"?

int i = std.regexp.find(foo, r"[^\\]#");

works as well

Where I come from, 'pound sign' has always meant ₤, and # is 'hash'. (BTW, what do you call ₤?)

Oh I guess that's called a pound sign too, but whenever you say "pound sign" here it means almost certainly #.  We might call ? a "British pound sign" or so.

I've oft heard it called a "Sterling".
