I answer myself, one way would be:
if $avar == undef { fail("'avar' not defined") }
I think that assertions would be even better:
assert($avar != undef)
or
assert($avar)
I think that add assertions would be a good idea. They could check
True/False conditions, if variables are defined or not, if objects are
defined... Is there any proposal about this?
