Hey @jvanleeuwen, sorry it took a while to get back to you, I am on holiday with no laptop(!). I think I see what you are trying to do, but it looks like your factory function is returning a new selector each time so you won't get the memoization benefit?
from reselect.
@jvanleeuwen, See reduxjs/react-redux#52 (comment) and reduxjs/react-redux#59 (comment). I think this direclty adresses your issue here. Also what ellbee said is correct. You will not get any memoization when creating a new selector every time you select the data from the state. Create the selector once and use it whenever needed.
As soon as reduxjs/react-redux#59 (comment) is merged, you could pass the created selector as part of the props of your component and use it in the mapsStateToProps function to select the memoized result of your selector.

@ellbee Thanks for reacting while on vacation ;)
@PSpSynedra @ellbee
Both you guys are correct. My example code was terrible ;)
I eventually solved my use-case with a HOC which I pass props and returns a mapStateToProps > Reselect based on these passed props.
Your idea of passing a selector in Props is pretty interesting. I will try that today
from reselect.
@jvanleeuwen, You are absolutely correct. I was completely ignorant to the parent prefix of the props parameter passed to the mergeProps function. The documentation does also make that pretty clear, sorry for the confusion.

Not a single problem, thanks for helping. This can be closed :)
