Suggested change

	* @return array[] Data provider.
	* @return array<string, array{ type_function: string }> Data provider.

[peterwilsoncc]

@westonruter It's a little mixed but currently it seems common just to add the simplified docs for the data provider to avoid the need to double up docs with the @params in the function above it. For example c4d8047#diff-09a2e7959959d6a08ef07b1849e0178b853f7ef86f7885bbf9be2ed261145b24R4215

[westonruter]

I don't feel strongly, but in new tests I've tried to be as explicit about the return types as possible. This makes it easier to understand at a glance what a data provider is expected to return, as opposed to analyzing the pattern in the data being returned. Granted, the data returned here is quite simple.
