To expand on this, yes, you can force Bash to read more lines and keep them in memory before executing them by wrapping them in blocks. These blocks can be (), {}, functions, and maybe other structures.
In addition to this, you can make sure no appended code is ever executed by explicitly running "exit" at the end of your block. I actually used this trick in a self git-updating script (the updated version could contain more lines at the end).
