Over in typing-sig we're considering a new syntax for callable *types*, which would look like (int, int, str) -> float. A matching syntax for lambda would use a different arrow, e.g. (x, y, z) => x+y+z. On Wed, Sep 29, 2021 at 11:51 AM Stephen J. Turnbull < stephenjturnbull@gmail.com> wrote:

Hence the proposal is to add a new syntax via the new token `?`.
I find that unreadable.
If you're going to add new syntax, either bite the bullet and just allow 'λ' for 'lambda' (my preference as an old lisper), or 'x → f(x)' (following MRAB's earlier suggestion). Or maybe omitting the function name from a def: 'def (x): f(x)'.
