In broadcast: Broadcasted Array Operations Like 'NumPy'

x.dim <- c(10, 2,2)
x.len <- prod(x.dim)

gen <- function(n) sample(list(letters, month.abb, 1:10), n, TRUE)

x <- array(gen(10), x.dim)
y <- array(gen(10), c(10,1,1))

bc.list(
  x, y,
  \(x, y)c(length(x) == length(y), typeof(x) == typeof(y))
)
