Sorry for jumping in late and following the discussion closely, but what about
not allowing statements and having something like below?
lambda `(' [parlist] `)' explist
I think this would cover most of the needs for a lightweight syntax. Taking a
recent snippet from Mark Hamburg, for example:
stream:map(lambda(x) x * x)
:filter(lambda(x) x % 2 == 0)
:subscribe(function(x)
total = total + x
log:writef("%d %d", x, total)
end)
Cheers,
Luis
