I totally disagree about assert being the same as a stack overflow in 
nature, but more importantly, you're ignoring the lessons learned from C++ 
and Java on the exception specification front.  You just don't know what 
exceptions code you call in a real program will throw in general.  There 
are plenty of times when you want to try something at runtime and just bail 
if it doesn't work, and you don't care about the specifics of why it didn't 
work.  A single "with _" will mask any assertions living below it, which 
seems to me to be a bad thing since by definition an assert is a 
development debugging tool.  Assert should just blow up, like in C (at 
least as an option).  You shouldn't have to remember to put a "with" clause 
in for it.
