I would not have a problem with you changing the shell to ensure syntax 
errors always terminate (though I cannot speak for others), but the 
problem is not limited to syntax errors, so that is not enough to fix 
the problem.

I do not understand this, not even with your followup e-mail. You 
changed my test in which the syntax error is non-fatal to one where the 
syntax error is fatal, and then conclude from that that you can assume 
syntax errors are always fatal? That does not work. If you have two 
tests with syntax errors, where the syntax errors are fatal in only one 
of them, that means you can *not* assume all syntax errors are fatal, 
and can *not* assume all exceptions are deadly.
