Go defines a built-in data type <code>bool</code>, which has exactly two values, represented by the keywords <code>true</code> and <code>false</code>. There is no conversion between booleans and other data types. Conditionals require a boolean value, so if i is a numeric type, for example, you must spell out <tt>if i != 0 {</tt> if you wish to interpret it as boolean. |

The template package however, uses a different rule for <tt>if</tt> actions. There, it is testing if a "pipeline" is "empty" where the empty values are false, 0, any nil pointer or interface value, and any array, slice, map, or string of length zero. |
