I don't have access to the Smalltalk Git, but if there's a consensus
that displaying `_` as a left arrow just like `:=` is a better choice,
I'll be happy to change it in the GNU ELPA package
(http://elpa.gnu.org/packages/smalltalk-mode.html)

Also I'm not sure it'd be helpful: the purpose of displaying `_` and
`:=` as an arrow is that it's meant to express the semantics in a more
intuitive way, whereas I don't know that "fingers" would express the
notion of comment more intuitively (also I'm not sure which Unicode char
would be used for that, but a quick look here with `C-x 8 RET` didn't
turn up anything covered by my currently installed fonts).
Nowadays coloring is more traditionally used to indicate that something
is a comment.

Similarly here, I don't see why a doubled up-arrow (I guess `⇑` ?)
would convey the semantics in a more intuitive manner than a `!`.
So I'm not sure it'd be worth the trouble.
