I find myself using brackets only if there will be more than 1 command...

Code:

if (something) {
  command1
  command2
  command3
}


but if only one command I don't use them...

Code:

if (something) command1


As for your stuff alias, don't forget to use elseif so every line is not processed...

Code:

stuff {
  if (something) command
  elseif (something) command
  elseif (something) command
}
