- Implement the visitor interface. This simplifies working with the AST, for example transformations into other IRs or collecting and analyzing various statistics. - Switch the explorer to use the visitor interface. - Add the reciprocal function name conversion for function names. - Some drive-by cosmetic fixes. --------- Signed-off-by: xermicus <bigcyrill@hotmail.com>
