I'm not sure what you want. Hopefully, this will help.

Thanks to indirect object syntax, 

catch Error::IO ...

[download]

is the same as 

Error::IO->catch(...)

[download]

Thanks to try and with's prototype, 

try {
   ...
}
catch Error::IO with {
   ...
};

[download]

is the same as 

try(sub { ... }, Error::IO->catch(with(sub { ... })));

[download]

(That's why the trailing ; is necessary.)

In fact, the following would work: 

sub stuff { ... }

sub err_handler { ... }

try \&stuff, catch Error::IO with \&err_handler;

[download]

try uses eval BLOCK to catch exceptions (i.e. calls to die). It determines what to do with the caught exception using the object catch returns. throw is a wrapper around die.
