# Folow-up on combining pure functions [duplicate]

This is a follow-up to this question. Consider:

f = #^2&
g = #^3&

Compose[f, g]
(#1^3 &)^2


Am I the only one to think this is a bug?

• Note that Compose[f, g] does return f[g], and that Compose[] has been obsolete for quite a while... – J. M. will be back soon Apr 7 '17 at 3:28
• Composition[f, g][x] evaluates to x^6 – Bob Hanlon Apr 7 '17 at 6:43
