#   Yes, you can execute this whole script for demonstration.

#   Of course you also remember comments, the here document, and the :
#   command, right? :-)  Okay, so I effectively (but not literally)
#   comment out the part between the pairs of __EOT__ without having to
#   individually comment out most or all the lines in the section.

>>/dev/null 2>&1 : << \__EOT__

#   { list } syntax:
	
	#	the syntax is a bit funky, one needs whitespace (one or more
	#	blanks, tabs, or newlines) between { and list, and list must
	#	either end in semi-colon (;), or there must be a newline between
	#	the end of list and }

E.g. these won't work:
(remember : is a "special" command (built-in, simply and efficiently,
returns zero))

{:}

{:;}

{:
}

{ :}

{
:}

__EOT__

# Whereas these all work:
{ :;}

{
:;}

{ :
}

{
:
}
