Just for a bit more backgroud:

block eval indeed had some not-totally-implausible corner cases, as 
listed here:
https://metacpan.org/pod/Try::Tiny#BACKGROUND

AFAIK at least some of them were fixed in Perl 5.14:

I personally don't like Try::Tiny, because it changes how 'return' works 
inside an eval (well, try), and I'm too stupid to remember this change 
(and it bit me a few times). OTOH I never (even on ancient Perls had any 
problem with three issues mentioned in Try::Tiny - Background (but then 
"die Dummen hams Glück" as a local saying goes)


And regarding using exceptions or not: I don't think you have a choice 
here. You will always encounter exceptions (disk full, DB-Server 
crashed, ...), so you might as well get used to them and incorporate 
them in your toolkit. I know nothing about .NET, so maybe exceptions are 
horrible there. But in Perl they work quite well, IMO...
