let unpack

[vis...@stanford.edu]

You can normally do

z = (1,2,3)

(a,b,c)  = z

and it will unpack things from z into a,b,c.

However, if you do:

let (a,b,c) = z; a end

it's a syntax error. Is there a way to get the spirit of this unpacking inside a let statement? I don't want permanent assignment in the function (I already get how to do that).

Eg: let a=nothing,b=nothing,c=nothing; (a,b,c) = z; a end seems like a bad choice. There must be some other way....

Thanks!

I think this should work. You should file an issue if there is
none yet.

let; (a,b,c) = (1, 2, 3); a end

(note the semicolon) works. But I think it should work as Mauro stated.

Yes, this should definitely work. I'm a bit surprised it doesn't already.
