If Foo[T] is synthesized implicit macro, then sometimes recursive calls from Foo[X] to Foo[Y] might lead to divergent implicit errors.

The build-in divergent expansion protection is nice, sure thing, but for macros it just gets in the way, because it's the macro programmer who should be in control.
