Add mutation for some literals * This is in progress code. The plan is to support all literals before beginning to cleanup and dedup the mutation generation. Have to understand the AST and the possible mutations more in depth before making structural decisions here. 2012-07-27 22:39:31 +02:00			`module Mutant`

Do not create empty blocks on mutations 2012-08-13 20:40:00 +02:00			`handle(Rubinius::AST::Block)`
Create namespace for literal mutations * Do not follow rubinius names anymore. An explict declaration now declares a mutator handles specific AST node. * Has a nice impact on metrics. 2012-07-31 19:45:46 +02:00

Cleanup and dedup mutation generation * Mutator and Generator where merged. * A single pass over all duplications was made. * It is clear a specific handles?(node) code for finding mutators is needed. Like virtus does for attributes, should also cache. * Does not pass on 1.9 mode currently as blocks are unexpectly parsed differend when it comes to a series of literal booleans. 2012-07-31 04:00:05 +02:00			`# Emit mutants`
