chore(*): minimize dependencies on tests Signed-off-by: Leonardo de Moura <leonardo@microsoft.com> 2014-08-24 19:58:48 -07:00			`import logic`
fix(tests/lean): adjust tests since module 'logic' depends on nat We need that because of the definitional package 2014-11-22 17:34:05 -08:00			`namespace experiment`
