[LC++]Exceptions vs. Errors

	I find I like exceptions because I tend to write functions that return 
something (like say an int) for which all the possible values are in 
fact valid, but there are still possible error conditions (like 
overflow) that need to be reported.  The only way to do this w/o 
exceptions is to use some perversion like errno.
	I can't say though that I'm in love with the syntax either.  The extra 
braces just seem to hurt formating to me.  I'm hoping I'll like what 
they are doing in perl 6.  It still needs braces, but any set will do.
