[Templates] Process vs Macro ?

One thing I don't see that anyone's mentioned is that when you PROCESS/INCLUDE a template that has MACROs and named 
BLOCKs _in_ it, you would call those differently:

File templates/myfuncs.tt2:

[% BLOCK thing1 %]
	[%# stuff %]
[% END %]

[% MACRO thing2() BLOCK %]
	[%# stuff %]
[% END %]

File templates/mytempl.tt2:

[% PROCESS myfuncs.tt2 %]

[% PROCESS myfuncs.tt2/thing1 %]
[% thing2() %]

Also, a BLOCK produces output.  A MACRO returns a value.  So you can also do this:

[% 'something' IF thing2() == 'whatever' %]

which wouldn't work with a BLOCK.

For both of these reasons, I hardly ever use BLOCKs unless they're going to a) only going to be called from the current 
template, and b) always going to produce output directly to the user.
