Note that Try::Tiny doesn't provide more than the "or do" pattern
It actually does, it preserves the value of $@, the following modifications to your script demonstrate the difference:
...;
eval { die "Foo!" };
# Exception details lost.
eval {
my $o2 = 'My::Obj'->new;
die "Exception!";
1 } or do {
warn "Caught with or: $@";
};
say "\$\@ after eval or do: $@";
# not same as above.
use Try::Tiny;
eval { die "Foo!" };
try {
my $o3 = 'My::Obj'->new;
die "Exception!";
} catch {
warn "Caught with Try::Tiny: $_";
};
say "\$\@ after try catch: $@";

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
