Or you could create an instance (via cfobject or createObject()) and then
call the method on that:
<cfset sub = createObject("component","sub.component")/>
<cfset res = sub.foo()/>

If it is in the same directory as the calling component, it could be
"package" (or at least the *method* you call could be access="package").
Otherwise it would need to be access="public".

You need to be a little bit more specific about what you're trying to do.
It is not a good idea to have components be 'environment aware', i.e.,
have them directly manipulate scopes such as "request". That limits the
component's usefulness.
How are you invoking the main component? How are you passing variables
into it?
I guess you could say (I haven't tried this):
<cfinvoke component="main.component" method="bar"
argumentCollection="#request#" returnvariable="res"/>
This makes every item in the "request" scope available in the "arguments"
scope inside "main.component". Then when you invoke the sub-component,
pass argumentCollection="#arguments#" to ensure all those items get passed
to the sub-component. Ugly.
