I would say that when lambda functions occurs in function calls I find the
\ or ==> syntax more readable.
To me, in that context, '==>' is the most readable as it does not have
parentheses on the argument. It's a bit visually noisy with them.
I concur, `==>` to me also stands out the most easiest to read without
too much parenthesis noise.
