I think you and Shalin are having a vocabulary problem.
you used the term "function" which has a specific meaning in Solr, if you
want to write a new function, which works with the existing Function
syntax solr provides, and can be nested inside of other functions, then
what you want to write is a ValueSourceParser. If you want to write your
own Query parser with an entirely new syntax (in which you want things to
look like function calls and produce query objects) then you need to
implement a QParserPlugin.
Some pointers about both can be found here...

: Within the function, the intent is to rewrite incoming parameter into a
: different query. Can this be done? AFAIK, not.
