Unfortunately, there is no introspection in Velocity.
One complicated idea would be to "meta parse your template".
The idea would be to use a kind of Velocity introspection on all your templates.
Each time this introspection encounter a variable, like ${a} or a, you replace
it with a "meta template" that would content ${variableName} and would produce
${a}.
So, finally, it would do the job for you.
The only thing you need is that Velocity introspection but as far as I remember
it doesn't exist.
