Amendment 2. Make the ~> operator non-associative
Why? Once you read documentation about how the operator works and what
it does, you will know it and writing the extra brackets seems
superfluos. And woudn't this complicate the parser even more? Also, if
you have no idea about functional programming whatsoever, this will be
hard to grasp in any syntax form, but the syntax isn't the problem in
that case (as I already said in previous email).
Yeah, maybe this one is just me - I just find right-associativity
really hard to read, whatever it's purpose. Maybe it's because I've
only ever read left-to-right languages.
As mentioned in a previous e-mail, when I look at "$a ~> $b ~> $c" it
makes me think of a single chain where all the terms are somehow
related, like "$a = $b = $c", rather than any kind of nesting. Maybe
I'd get used to it, maybe it would be rare enough that I'd never need to.
So you are taking a syntax that's supposed to be short and "clean" and
making it more complex by the amedments 3 and 4?
No, I'm trying to think of compromises which address constructive
criticisms people have made of the current proposal, such as the
variety of syntax forms, and the implicit scoping of variables.
To be clear, these are not demands or anything like that, just
suggestions of how to move the discussion beyond "here's the proposal,
take it or leave it".
Really appreciate that! Like the idea but the variation in syntax forms
is a bit confusing. Maybe one start with a very simple function and as
as you expand it the syntax form needs to change which I think is a
drawback.
