I've actually changed my mind so that I don't mind using parens, but only for function calls. Calls to a vau (def, if, and, let, etc.) shouldn't be wrapped in parens:
mac accessor -> n v
uniqs %a
{def n -> %a
{{%a v} %a}}
def or: casevau env
x -> (eval x)
x @r -> let x (eval x)
if x x (eval {or @r})
The above is a hypothetical mockup for new syntax for Nulan. It's radically different than the current syntax, but I think it looks very clean. At least, compared to the current syntax:
$mac accessor; N V ->
$uniqs %A
[$def N; %A ->
[[%A V] %A]]
$defvau $or Env
X -> eval X
X @R -> $let X: eval X
$if X X: eval [$or @R]
