+# 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.
