May I suggest that a third split function be offered.  In VB(.net) there is
the option to split and limit the number of returned parts, eg:

dim str as string = "QAZ = Test Log value = 5"
dim parts as string()
parts = str.split("=", 2)

This results in parts(0) = "QAZ " and parts(1) = " Test Log value = 5"

I find this incredibly useful in log file and other text manipulation work.

So the D equivalent should be:
char[][] split(char[] s, char[] delim, int parts)

Thoughts?

It's usefull.
I needed it.
I use it (just rejoin after split).
let's got for it.

I don't know.
meanwhile you can use this crude implementation:

char[][] split (char[] string, char[] delim, int parts)
{
	char[][] tks = std.string.split(string, delim);
	if ( parts>0 && tks.length>parts )
	{
		tks[parts-1] = std.string.join(tks[parts-1..tks.length],delim);
		tks.length = parts;
	}
	return tks;
}
