I think you'd want to do this:

[% tempbaz = "blah" _ ANOTHER_VARIABLE %]
<td>[% foo(bar="blah", baz=tempbaz) %]</td>

The parser doesn't much like inline string construction in calls, you 
normally need to build the argument first in a single variable and then 
pass that.

You almost never want to nest your tags like this:
  [% somthing ... [% variable %] ... %]
instead you mostly want to refer to the variable directly
  [% somthing ... variable ... %]
or indirectly
  [% somthing ... $variable ... %]
