lazy doesn't work with always instead of (\_ -> ..) #50

Hello, I have ran across this

This works:

parser : Parser ()
parser =
    Parser.lazy (\_ -> parser)

But this

parser : Parser ()
parser =
    Parser.lazy (always parser)

throws error Thexvalue is defined directly in terms of itself, causing an infinite loop. image

I guess it would be enought to add a Hint about it so that if someone runs linto this he doesn't have to debug it.
