That would defeat the purpose of _Uniform_ Function Call Syntax.
The whole point is that it uses the same syntax for member
functions and free functions. In many cases, it's just for
aesthetic purposes, but with templated code, it can be critical,
because it allows you to effectively overload a free function
with a member function (e.g. a particular range type could
overload find if it had a more efficient implementation for it
than the one in std.algorithm). It also makes it so that a type
which doesn't have member functions can work in a template that's
expecting the type to have specific member functions (e.g. arrays
use free functions for the range primitives, but they're normally
used as if they were member functions).
