try_ catch_ Statement

#include <boost/phoenix/statement/try_catch.hpp>

The syntax is:

try_
[
    sequenced_statements
]
.catch_<exception_type>()
[
    sequenced_statements
]
...
.catch_all
[
    sequenced_statement
]

Note the usual underscore after try and catch, and the extra parentheses required after the catch.

Example: The following code calls the (lazy) function f for each element, and prints messages about different exception types it catches.

try_
[
    f(arg1)
]
.catch_<runtime_error>()
[
    cout << val("caught runtime error or derived\n")
]
.catch_<exception>()
[
    cout << val("caught exception or derived\n")
]
.catch_all
[
    cout << val("caught some other type of exception\n")
]
