Controles evaluation of identifiers / variables
[ string ]
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 ]
This would echo "%a" since %b is evaluated once. Note that this is the same as just echoing %b
echo -a [ [ %b ] ]
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 ] ]
This would echo "sometext%a" In this case %a is evaluated once and so is %b. Note that echoing [ %a $+ %b ] will not work.
echo -a [ %a $+ [ [ %b ] ] ]
This would echo "sometextsometext" since %a is evaluated once and %b twice.

Another example:
var %name = fish
var %surname = bot
[[set]] % [ $+ [ %name ] $+ . $+ [ %surname ] ] m00
This would set %fish.bot to m00.
