In broadcast: Broadcasted Array Operations Like 'NumPy'

# maths ====

x <- 1:10
broadcaster(x) <- TRUE

y <- 1:10
broadcaster(y) <- TRUE

x + y / x
x + 1 # mathematically equivalent to the above, since x == y
(x + y) / x
2 * x/x # mathematically equivalent to the above, since x == y

dim(x) <- c(10, 1)
dim(y) <- c(1, 10)

x + y / x
(x + y) / x

(x + y) * x


# relational operators ====
x <- 1:10
y <- array(1:10, c(1, 10))
broadcaster(x) <- TRUE
broadcaster(y) <- TRUE

x == y
x != y
x < y
x > y
x <= y
x >= y
