DMD v2.069.2-b1 on Linux.

     import std.algorithm;

     int a = max(5, 6);            // works, a == 6
     int b = max!(int, int)(5, 6); // works, manual instantiation
     int c = 5.max(6);             // works, UFCS call

I would like to use the last syntax, but with an alias.

     alias butAtLeast = max;   // works
     int d = butAtLeast(5, 6); // works
     int e = 5.butAtLeast(6);  // error: no property 'butAtLeast' 
for type 'int'

Aliasing the instantiated function 'max!(int, int)' instead of 
aliasing 'max' doesn't help: The 'int e' line will fail with the 
exact same error.

Can I get the alias to work somehow in an UFCS chain?

By putting it in the top level. I believe this is intentional but 
I don't remember the reasoning.

This is due to limitation of function-local aliases. If you put 
the alias outside it will work: 
http://dpaste.dzfl.pl/4fb06cbbfad2.

Perhaps a simpler way achieve this is to use renamed imports:

The Identity template can also helpful in some situations:

Thanks for both of these quick replies -- doing it similar to 
that example, it works for me too now. Good to know this little 
workaround.

I'd love to see the design reason for the limitation. Right now, 
the error message (property doesn't exist at all) seems to be 
misleading. But getting all corner cases right is always tricky.

Thanks, will read for inspiration!
