forgot to add:
of course the error is that 'foobar()' doesn't compile, but the error message
provided completely hides that, and is confusing, since user did define
opSlice.
I'm guessing implementation uses something such as __traits(compiles, expr) to
check whether user defined the template and error gagging prevents showing it.

Either way, as it is, in larger programs, it can be very hard to figure out the
reason of the bug given poor compiler msg
