     method_log <method-signature> # e.g. Foo::Bar#baz
 
 ### Todo
 
 * Support earlier versions of Ruby (it ought to be possible to support down to v1.9.3 fairly easily)
+* Investigate whether parser gem can only parse source code written using the current Ruby version
+  * It would be nice to have a better error message if parsing fails
 * Support for Rspec tests
 * Default to looking for commits in current git branch
 * Maybe add as new git command or extension to existing command e.g. `git log`
 * Optimise search for method definitions:
-  * Only consider commits where file that last contained method has changed
   * First look in file where method was last defined
+* By default stop when method disappears from history
 * Find "similar" method implementations e.g. by comparing ASTs of implementations
