[fpc-pascal] using exceptions

Because much used routines like strtoint are often used without proper
checking. So strtoint throws exceptions, and people that want to handle
errors properly use trystrtoint.

Roughly the same as you. Few exceptions, and usually when in to abort fairly
deeply nested code.
