Bug in parenthesis based execution

[LadyCailin]

The following code causes a repro:

register_command('astralproject', 
  array(

    'description': 'Use it like /locate', 
    'usage': colorize('&cExample: /astralproject structure village_desert'), 
    'permission': 'command.astralproject', 
    'noPermMsg': 'Sorry you don\'t have permission to use this command.', 
    'executor': closure(@alias, @player, @args) {

      if(array_size(@args) != 2){
        return(false)
      }

      @tasks = array(
        array(1000, closure() {
          tmsg(@player, 'Meditating...')
          set_peffect(@player, 'DARKNESS', 1, 7, true, false)
          set_peffect(@player, 'BLINDNESS', 1, 7, true, false)
        }),
        array(1000, closure() {

            @executeTaskContainer[0]()
          })
        }
      }

This can be reproduced through example program:

@closureArray = array(closure() {
    console('This does not execute.')
})
console('This executes.')
@closureArray[0]()
console('Code below execution required for the bug to occur.')

Running optimizer-test on this program and manually formatting it results in:

__statements__(
    assign(@closureArray, array(closure(console('This does not execute.')))),
    console('This executes.'),
    array_get(@closureArray, 0),
    __autoconcat__(),
    console('Code below execution required for the bug to occur.')
)
