This one sounds like a brilliant idea.
Its looks like a short form for:
<tmpl_unless name="param_name">my_default</tmpl_unless>
changes to:
<tmpl_var name="param_name" value="my_default">
It would certainly make some templates a lot cleaner.

woohooo :-)
Here is a patch i submitted a whlie ago that does nothing but a
'__counter__' variable if loop_context_vars is set.

default) four loop context variables are made available inside a loop:
__FIRST__, __LAST__, __INNER__, __ODD__. They can be used with
<TMPL_IF>, <TMPL_UNLESS> and <TMPL_ELSE> to control how a loop is
! output. Example:
<TMPL_LOOP NAME="FOO">
<TMPL_IF NAME="__FIRST__">
This only outputs on the first pass.
</TMPL_IF>
<TMPL_IF NAME="__ODD__">
This outputs every other pass, on the odd passes.
