You
shouldn't rely on try/catch for algorithm implementation.

You create exceptions for errors and unexpected behavior. Then in some
other
part of the system you use try/catch to prevent the code from
terminating
abruptly. You catch the exception (you should know which exceptions
can be
thrown), and act accordingly. Either closing resources, add a log
message
with debug information, and/or sending an error message to the user.

Except that once you start trying to integrate several large bodies of
code, you have NO IDEA what exceptions can be thrown, and even less
idea where they didn't get caught and handled properly.

Worse, many times the library[ies] you are integrating to an abysmal
job of doing anyting intelligent with the catch block, and you're
stuck with something even worse than set_error_handler.

try/catch works great for small/medium projects, or even large
well-documented projects perhaps, but as soon as you start trying to
integrate several projects...

Well, in MY experience, try/catch just ended up biting me in the butt...
