If  you realize that aliasing is mostly analogous to #define in
C-and-friends, this becomes less horrifying.  It's little more than a
built-in preprocessor.

In this case it means any unfinished complex code structure -- "if"
without "fi", "do" without "done", "case" without "esac", "foreach"
without "end".  Mathieu wants execution to begin as soon as there is
some code in the buffer, without waiting for the final keyword to
appear.
