I must be missing something here - but are non-positional arguments not permitted on the init proc? A transcript of my attempts below...

Dear Shishir,
The recommendation is, not to use nonposargs in init, since providing values in the "-" syntax conflicts syntactically with object configuration.
You can use nonposargs in "init" it with some more syntax like in the following example e.g. in factory methods:
Class foo -parameter {{-a "apple"}} foo instproc init {{-a "apple"} args} { puts a=$a} foo f foo f [list -init -a "banana"]
