Controles evaluation of identifiers / variables
The evaluation brackets work a bit like [[$eval]] though you can add multiple things to evaluate at different levels at once.

Example:
  [[var]] %a = sometext
  var %b = % [[$|$+]] a
Now %a is "sometext" and %b is "%a"
  [[echo]] -a [ %b ] returns ''%a''
This would echo "%a" since %b is evaluated once. Note that this is the same as just echoing %b
  echo -a [ [ %b ] ] returns ''sometext''
This would echo "sometext" since %b is first evaluated to "%a" and then %a is evaluated to "sometext".

Now lets see how it works out in more complex forms.
  echo -a [ %a $+ [ %b ] ] returns ''sometext%a''
This would echo "sometext%a" In this case %a is evaluated once and so is %b. Note that echoing [ %a $+ %b ] won't work.
  echo -a [ %a $+ [ [ %b ] ] ] returns ''sometextsometext''
This would echo "sometextsometext" since %a is evaluated once and %b twice.


Another example:
  var %name = fish
  var %surname = bot
  [[set]] % $+ %name $+ . $+ %surname m00
  echo -a % [ $+ [ %name ] $+ . $+ [ %surname ] ] returns ''m00''
This would set %fish.bot to "m00" and echo "m00".
