optgen's Issues

generate With* methods with variadic arguments

Right now slice fields generate two methods:

• Set<FieldName>
• With<FieldName>

The ergonomics could be improved for slice fields if we make With take variadic argument. This spares the developer the need to create a slice of predefined values like SetFieldName([]MyFieldType{value1, value2}) and write a more ergonomic WithFieldName(value1, value2). Any calls to the previously generated With methods would be backward compatible for those that only set a single value.
