improve syntax of unquote ($)

[zingales]

currently the "unquote" is $.

However, this conflicts with the $ operator, so the answer to

for i = 1:10
    quote
        $(array[i])[
    end
end

is unsure.

also operations like

for
   quote 
        count$i = name$i (or)
       $(count[i])[2]

   end
end

will not do what you want/think it will do

These examples are unclear or mis-entered. I've never encountered issues with $ myself.

I think the fix we want is to be able to use $(expression) like we can in string interpolation. Right now $() is parsed as a function call. I guess writing the function call version inside quote will need ($)().

[StefanKarpinski]

While you're at it, can you make $ expression interpolation ungreedy like $ interpolation in strings and commands are?
