Values not saved with Must... methods about ini HOT 3 CLOSED

I have found the reason, sorry.

The ini.Key([key_name]).Must*([default_value]) methods do NOT set the value of the key to the default one passed.

Such behaviour is very inobvious...

1. ini.Key([key_name]) creates the key if it does not exist
2. However, the default value is not set with a Must* method.
   One ends up with an always existing key, but it may have no value!

Probably, it may be a good idea to provide a method like
func (s *Section) GuaranteeKey(key, defaultValue string) *Key

1. If the key does not exist it is created and the default value is assigned
2. The method returns either the prexisting key or the newly created one

Good point!
