Way to create multiline comments in Bash?

Question

I have recently started studying shell script and I\'d like to be able to comment out a set of lines in a shell script. I mean like it is in case of C/Java :

Simple solution, not much smart:

Temporarily block a part of a script:

if false; then
    while you respect syntax a bit, please
    do write here (almost) whatever you want.
    but when you are
    done # write
fi

A bit sophisticated version:

time_of_debug=false # Let's set this variable at the beginning of a script

if $time_of_debug; then # in a middle of the script  
    echo I keep this code aside until there is the time of debug!
fi
