Description
Even when following the exact code from the 5.34 perlsyn docs regarding producing a default value with a try/catch block wrapped in a "do" block, the code fails to produce the value.
Steps to Reproduce
#!/usr/bin/env perl
use 5.034;
use feature 'try';
no warnings 'experimental::try';
my $result = do {
try {
1 / 0;
} catch ($e) {
warn "Error: $e";
1;
}
};
say "'$result'";
Expected behavior
It outputs:
Error: Illegal division by zero at try_catch.pl line 9.
''
It should output:
Error: Illegal division by zero at try_catch.pl line 9.
'1'
EDIT: If you remove/comment the warn line, it works as expected.
