broadcasting

All functions are automatically broadcasting on lists and pair values:

square number=number*number
square [1 2 3] == [1 4 9]

square [a:1 b:2 c:3] == [a:1 b:4 c:9]

delete file = run `rm $file.name`
delete all files in ls /   # 🧐

Even though the map functor is part of angle, in 99% situations it should be superfluous via all/iteration as seen above.

Broadcasting reduces the amount of cases where function pointers are necessary.

Just use square [1 2 3] == [1 4 9] instead of map &square [1 2 3] == [1 4 9]

folding multiple arguments

An interesting special case might be if functions take more than one argument: int sum(int a, int b) { return a + b; } sum [ 1 , 2 , 3 ] MIGHT be treated as sum(1,sum(2,3)) // depending on the associativity or the operator left or right folding or it doesn't matter

Interesting or bad idea ?

ambivalence

Broadcasting applies to functions but not to basic operators:

[1,2,3]+4 == [1,2,3,4]
[1,2,3]>>1 == [2, 3]
[1,2,3]++ == [2, 3]

In these cases one does have to use the keywords [[map]] or [[each]] or wrap the operator into it a [[closure]]:

map [1,2,3] {it+1} each [1,2,3] {it+1} [1,2,3] {++} // dodgy

MAYBE we adopt ruby style symbols for function pointers too:
map [1,2,3] :++
