I know you want to keep this lightweight, but I have a few more ideas:

Allow $(count formatter=myFormatter) where myFormatter is a function you 
provide in a dictionary of functions like so: formatters = 
{'myFormatter':myFormatter}.  Then you can support whatever funky number 
and date formats you want.

Also, how about allowing types and classes in there too as "default" 
formatters for those types?  formatters = {types.IntType: myIntFormatter, 
MyClass: myClassFormatter}

And finally, how about allowing just a single value in valueContainers 
instead of a list.

So here's an example that shows all my desired features :-)

rnv = replaceNamedValues

foo = 'foo'
bar = 24
qux = someFunctionThatReturnsADict()
def fooFormatter(x):
         ...
def intFormatter(x):
         ...
def flimflamFormatter(x):
         ...
print rnv('foo = $(foo formatter=fooFormatter); bar = $bar; qux.flimflam = 
$qux.flimflam',
           locals(),
           formatters = {'fooFormatter': fooFormatter,
                         types.IntType: intFormatter,
                         FlimFlam: flimFlamFormatter})
