Hello.

We are using Try::Tiny module in our project. I'm always using "try" instead of "eval" whenever I can, but eval can do some things, that "try" cannot: it's evaluation code from strings.

So, when I use eval() with string I should do something like this:

eval "require $module" or $self->error("...");

instead of nice and pretty

try 
    "require $module" # It's not going to work
catch {
    $self->error("...");
}

[download]

I can try something like this:

try {
    eval "require $module" or die $@;
}
catch {
    $self->error("...");
}

[download]

but it still looks ugly, because it's actually eval{eval""}.

Should I worry about this? Should I suggest improving Try::Tiny so it can "try" strings, not only blocks?

P. S. I believe the root of the problem is perl "eval" itself. It does two things for me (evaluate strings AND catch "exceptions") that are not really connected.
