Well... I think use a name as CreateSpecialTMyObjectInstance() is very
especific... but, as you said, in the end it is all about personal

I think found a better way to my example. Instead to create an object
using Parser.CreateMyObj(ATxt), e.g., maybe is better have an object
(TMyObj) instantiated in Parser and the name of method would be
Parser.GetMyObj(ATxt). The Parser fill the FMyObj field (atributte)
using the ATxt parameter. Like as DataSet.FieldByName('column_name')
returns a TField object.

I use this style a lot, but I wanted to hear some better ideas.
