<description>
Calls a function and catches an error that can be thrown while the execution of the call.
<bug issue="2036">This cannot stop errors from hooks called from the engine.</bug>
<bug issue="2498">This does not stop <page>Global.Error</page> and <page>Global.ErrorNoHalt</page> from sending error messages to the server (if called clientside) or calling the <page>GM:OnLuaError</page> hook. The success boolean returned will always return true and thus you will not get the error message returned. <page>Global.error</page> does not exhibit these behaviours.</bug>
