I born in 1994. So, no chance of suggestion in 1991.
It is not about the keystrokes. Its about the visual cluttering. (and yes
it can save two keystrokes too and also four on Seven R. Kuze keyboard :-) )

As I have been stated in the Subject. My idea is only about function
definition, not function calling.

For readability (Readability counts).

Some people argued that function definition with parenthesis seems to them
natural. But actually it seems to us natural, because we have been used to
it a-lot. IMHO parenthesisless functions definitions are natural and
readable.

The Zen also says:

I think empty parenthesis for no apparent reason does not make any sense.

When I was a beginner, I found that it was very helpful that I *always*

We are beginner only for once and expert for life.
Between you can asked in your novice level, that why there are empty
parenthesis if a function don't have parameters?
