No. Any function attribute can go on either side, and which side they go on is 
generally personal preference.

const is a funny one though (as is immutable), since putting it on the left is 
the same as putting it on the right (as with all of the other attributes), but 
this can throw you off, because you might think that it's part of the return 
type when it isn't. e.g.

const C func() {...}

is the same as

C func() const {...}

If you want the return type to be const, you need to use parens:

const(C) func() {...}

So, it's generally considered good practice to put const and immutable on the 
right-hand side.
