I actually *do* think λ is a little bit more readable. And I have no idea
how to type it directly on my El Capitan system with the ABC Extended
keyboard. But I still get 100% of the benefit in readability simply by
using vim's conceal feature. If I used a different editor I'd have to hope
for a similar feature (or program it myself), but this is purely a display
question. Similarly, I think syntax highlighting makes my code much more
readable, but I don't want colors for keywords built into the language.
That is, and should remain, a matter of tooling not core language (I don't
want https://en.wikipedia.org/wiki/ColorForth for Python).
FWIW, my conceal configuration is at link I give in a moment. I've
customized a bunch of special stuff besides lambda, take it or leave it:
Keeping medicines from the bloodstreams of the sick; food
from the bellies of the hungry; books from the hands of the
uneducated; technology from the underdeveloped; and putting
advocates of freedom in prisons. Intellectual property is
to the 21st century what the slave trade was to the 16th.
