Consider a more descriptive keyword instead of "let"

[stasm]

let is clear enough, but I think we have an opportunity to use a keyword that directly relates to the name that we choose for these let bindings (#248). This would be self-explanatory and easier to learn and search for. For example:

local $foo = {$count :number}   // ...and call them "locals"
alias $foo = {$count :number}   // ...and call them "aliases"
macro $foo = {$count :number}   // ...and call them "macros"
decl $foo = {$count :number}    // ...and call them "declarations"
expr $foo = {$count :number}    // ...and call them "named expressions"

This is related to #248. CC @mihnita @echeran @eemeli.

I think let is fine, as it says "immutability" (if you come from JS, if not, then "tough luck")

From your list I also like macro and alias, as they are suggest "things you declare for convenience, something shorter, that you use to not repeat again and again something long"

The rest (decl and expr) are too generic.

And I think that macro and alias are more familiar than let, for a lot more people than JS devs.

I think macro comes with its own baggage related to how macros are usually implemented through expansion during the compile time. It might be too prescriptive for our purpose.

Regardless of the name, do you think there's value in aligning the name with the keyword, e.g. locals defined with the local keyword? Or are you fine with, say, named expressions defined with the let keyword?

[eemeli]

One reason I rather like let is that it doesn't directly relate to the name of these bindings; another is that it's a complete, short word rather than an abbreviation. However, my opinions on this are not particularly strong, at least atm.

[echeran]

To summarize, I prefer calling these things "named expressions", and using either let or expr sounds good to me. More details in #248, and +1 to @markusicu's comment there.

Totally fine with let
In fact if you ask me to vote, I would probably vote let, alias, macro (in this order).

[stasm]

It looks like there's enough support for continuing to use let that no changes need to be discussed for now.
