Details

Yash rejects the following script as syntax error: 

  1.  alias fori='for i ' do=';'
  2.  set 1
  3.  fori do echo $i; done

However, this script should print "1" without error. Alias substitution should not be applied to "do" because it is a reserved word.

Another alias-related bug. In the POSIXly correct mode, an unquoted "esac" cannot be the first pattern in a case list even if it is preceded by "(". The following script should be rejected: 

  1.  alias CASE='case esac in ( ' ESAC='esac'
  2.  CASE ESAC ) echo esac; esac
