Consider this example:

It's not that easy to distinguish from
quux (y . (foo>.< bar) . baz (f . g)) moo
Yeah, that's why I dislike dot as compose operator (^_~)
Me too. Though I've been told repeatedly that we're in the losing camp :(
Given that we want to apply selectors to entire expressions, it seems
more sensible to consider the selector syntax to be a prefix onto the
selector name. Thus, the selector would be named ".baz" (or ":baz",
"#baz", "@baz",...), and conversely any name beginning with the special
character would be known to be a selector. Therefore, a space preceding
the special character would be optional, while spaces following the
special character are forbidden. This has a nice analogy to the use of
":" as a capital letter for symbolic names: function names beginning
with the special character for record selectors just indicate that they
are postfix functions with some mechanism to handle overloading (whether
that be TDNR or whathaveyou).
