Proposal for Streamlined Error Handling in Go

This is a proposal for a way to simplify the error handling in Go.

The idea is to use attempt{} and recover{} blocks to separate the happy path from the error handling. NOTE: this is NOT exception handling as you would see in Java or PHP. More on why below.

In this proposal Go would allow the developer to omit capturing the last returned variable from a function call if and only if that call was within a attempt{} block. The Go compiler would handle providing access to the error instance via the geterror() function within the recover{} block if any function returns a non nil error as its last omitted parameter, i.e.:

attempt{
 data:= GetData()

$answer_fragment = $wpdb->prepare( '`answer_name` = %s', $new_answer );
$wpdb->compose('UPDATE %s polls SET vote = vote+1 WHERE %s AND %s',

Example use of do {...} while(false)

See this gist for background.

This example comes from my work here when looking for a solution for this issue related to this WordPress plugin.

I recognized I could make it clearer using the do {...} while(false) pattern so I wanted to document here.

Note:

            $args = wp_parse_args( $args, array(

            ) );
