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"]
