# WDTE only has expressions, not statements, so statement vs.
# first-class context doesn't make sense.

# Arguments in WDTE are technically passed by reference, in a way, but
# because it's a functional language and everything's immutable
# there's no real usability difference from that.

# Partial application is possible. For example, the following
# evaluates `+ 3` and then passes 7 to the resulting partially applied
# function.
