- !ruby/struct:SM::Flow::P
body: "Log a message if the given severity is high enough. This is the generic logging method. Users will be more inclined to use #debug, #info, #warn, #error, and #fatal."
- !ruby/struct:SM::Flow::P
body: "<b>Message format</b>: <tt>message</tt> can be any object, but it has to be converted to a String in order to log it. Generally, <tt>inspect</tt> is used if the given object is not a String. A special case is an <tt>Exception</tt> object, which will be printed in detail, including message, class, and backtrace. See #msg2str for the implementation if required."
