Description

julia> :(($+)(1,2))
:((+)(1,2))

julia> :((+)(1,2))
:(1 + 2)

The printing for expressions should take into account whether something is an actual function spliced into the AST or just a symbol and print the former with a $.

Contributor guide

Research direction
Investigate how the expression printer handles spliced functions ($) in the AST. Trace the printing code to see where the decision is made to omit the $, and modify it to include $ when the head is a spliced function call.
