Agreed re {. }.

I suppose an APL-er, familiar with up- and down-arrows for take and drop,  might

not appreciate the mnemonic nature of {. and }.  .... but I started with APL and don't

recall any problem with remembering/recognising these J symbols.

Learning problems enough elsewhere, though!

I then poked around a bit, and noticed in
https://vector.org.uk/j-ottings-59-love-actuarily/ a comment which
bemused me:

"(Personal note: I have at times struggled to remember the difference
between the symbols for ‘take’ and ‘drop’. The best I can suggest is
that the character ‘}‘ looks slightly like a poorly scrawled ‘dr’.)"

It seems to me that since in { } the { is on the left and the } is on
the right that it should be pretty easy to remember that the result of
{. comes from the part that's to the left of the part that the result
of }. comes from.

But I'm probably overlooking something important -- I usually do...

Thanks,
