I don’t really like the sound of this personally.

PureScript already decided coherence was an important thing, and correspondingly disallowed orphan instances entirely. It would be a little odd to then go ahead and introduce implicit parameters which are incoherent by design.

I guess you could argue they’re meant to solve different problems, so the same logic might not apply to both, but I’d need to see some good arguments to show that the convenience is really that much better than the alternatives.
