Ok. I see my folly. At compile time, there would not be any "this" since
the class has not been instantiated yet.

I will have to think of other solutions. Basically, I am trying to use the
parser to create functions that I can use at run time. But I wanted to
create two functions from the same parser. I have succeeded with creating
one function. I do not want to create two separate parsers because each of
these parsers would add to memory footprint of the compiler.

Any ideas? Maybe I could use tuples here?
