immutable(ubyte)[4] and immutable(ubyte[4]) are the same type. As a
consequence, this won't compile:

alias immutable(ubyte)[40] Hash;
Hash[] hashes;
hashes.sort;

.sort (std.algorithm.sort too) does not compile, as it thinks the array
contents is immutable.

Wrapping the array in a struct causes .sort to work, but not
std.algorithm.sort. Now I'm not sure what the bug is.

This is expected. The values of the array are immutable, so you can't swap them. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

Please show the code that shows the difference. Also, never use the built-in sort, it's quite buggy, and it's going to be deprecated, hopefully warned-against in dmd 2.066. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------

I have found it, filed as Issue 12253 I close this Issue because I think it's not a bug. -- Configure issuemail: https://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
