.SH DESCRIPTION
.IX Header "DESCRIPTION"
This module is a simple wrapper around \f(CW\*(C`Try::Tiny\*(C'\fR, which see. It
re-exports \f(CW\*(C`try\*(C'\fR, \f(CW\*(C`catch\*(C'\fR, and
\&\f(CW\*(C`finally\*(C'\fR.
.PP
In addition, it provides a way to catch only some exceptions by filtering on
the class (including superclasses and consumed roles) of an exception object.
.SS Functions
.IX Subsection "Functions"
.IP "catch_case ($;@)" 4
.IX Item "catch_case ($;@)"
Intended to be used instead of \f(CW\*(C`catch\*(C'\fR in the second
argument position of \f(CW\*(C`try\*(C'\fR.
.Sp
Instead of a block it takes a reference to an array of \f(CW\*(C`CLASS => CODEREF\*(C'\fR
pairs, which it passes on to \f(CW\*(C`dispatch\*(C'\fR in
\&\f(CW\*(C`Dispatch::Class\*(C'\fR.
