Let name=value...

The 'let' tag is used to bind variables to values within a block.

The text enclosed in the let tag is rendered using information
from the given variables or expressions.

For example::

  <!--#let foofunc="foo()" my_bar=bar-->
    foo() = <!--#var foofunc-->,
    bar = <!--#var my_bar-->
  <!--#/let-->

Notice that both 'name' and 'expr' style attributes may be used to
specify data.  'name' style attributes (e.g. my_bar=bar) will be
rendered as they are for var/with/in/etc.  Quoted attributes will
be treated as Python expressions.

Variables are processed in sequence, so later assignments can
reference and/or overwrite the results of previous assignments,
as desired.
