"read" LED state

While I can maintain the state of the LED in the JS impl - I would like to be able to just read the register for the digital pin connected to an LED

Arduino seems to support reading from and OUT pin
https://stackoverflow.com/questions/6160963/how-can-i-digitalread-a-pin-that-is-in-pinmode-output

But this does not work the same/expected way in Espruino:

pinMode(5, 'output')
=undefined
digitalWrite(5,1)
=undefined
digitalRead(5)
=0

I can sort of get what I want by using pin auto mode and making sure that every read writes back itself like this:

pinMode(5)
digitalWrite(5,1)
var x;
x = digitalRead(5); digitalWrite(5,x)
x
=1

But I was thinking there should be a way I should just be able to read the state?

I'm guessing I could use peek* functions to get at the register directly? But that seems very un-espruino like from a dev-ux POV

Any ideas on the right solution here?
