Variables within interpolated strings about guacamole HOT 6 CLOSED

Closing this. using the following quote by @gonzus which I very much agree with:

[...] maybe is doesn't make sense to try to restrict what can be done during interpolation. It could be both easier and more useful to just allow any Perl code in there, with whatever syntax you wish, including @{[...]}. [...]

You could also go the full monty, a la JavaScript:

    let foo = `bar ${ baz() + " is awesome"} baby`

where everything inside ${} (inside backticks) gets run as JS code.

We wouldn't be able to do it with ${} because that's syntax in Perl for scalars: ${var} is equivalent to $var.

This is kind of what we're doing in @{[ ... ]} though. Raku allows stuff like that though with {}.

In any case, I don't want to introduce anything else, only to pick what to support and how.

What I was trying to say is, maybe is doesn't make sense to try to restrict what can be done during interpolation. It could be both easier and more useful to just allow any Perl code in there, with whatever syntax you wish, including @{[...]}. I am not trying to introduce any new syntax.

@{[ ]} would work if we allow prefix dereferencing and interpolation of dereferencing. Those are two tall orders. We could do it, but maybe at a later phase.

Just saying I wasn't making a call here. Just suggesting that we don't have to support it immediately. (Maybe we can. Maybe we want to talk about it first.)
