Structured declaration & assignment fails

[brakmic]

Describe the bug

This example from language docs can't be compiled.

namespace NSMain;

entrypoint function main(): Int {
  {f=let x, g=@[let y, let z]} = {f=1, g=@[2, 3]};
  return y;
}

It fails with: Parse error -- ["declarations.bsq",6,"Literal match is not allowed"]

Minor syntax changes here too. I'll do a quick update in the docs as well.

entrypoint function main(): Int {
{f=let x, g=[let y, let z]} = {f=1, g=[2, 3]};
return y;
}

Awesome! Many thanks!
