The point is applicable to *everyone*:

   "Don't present code that you haven't actually
    run unless you *say* that you haven't run it."

You'll just end up confusing the OP or other readers that may benefit  
from
the code.  If you're trying to illustrate a point or an approach, say so
or make it quite clear that your code is incomplete or intended as
pseudo-code (particularly if it appears to be valid syntax).
