D2: std.algorithm.find, but get part before what you were searching for

std.algorithm.find() returns the rest of the range starting at what you were 
searching for (or an empty range if it wasn't in the given range). Is there  
a function in phobos which does a find but returns everything _before_ what 
you're searching for?

I can't find one that will do that, and I don't see an obvious way of 
combining functions to get it. Naturally, I'll roll my own function for it 
if I have to, but if there's already a way to do it in phobos semi-cleanly, 
I'd probably prefer to do that. So, I'm enquiring as to whether anyone here 
knows of such a function or combination of functions. Thanks.
