Interesting. JavaScript programmers that I’ve known bemoan that their 
language uses function scoping rather than block scoping.

That also seems incongruent with the built-in block scoping for try/CATCH.

Has Perl 6 embraced function scoping as a major paradigm, then?

But, what is the point of $! at all? The exception is given to the CATCH 
block as $_. If I want access to it outside CATCH, isn’t the expected 
workflow to save CATCH{$_} to a variable, the way my example does it?

$! is also not mentioned here: http://perl6intro.com/#_exception_handling
