[Scilab-users] Dump the output of a function

[Clément David]

Hello Christian, Samuel,

My 2c, most of the modern languages supporting such a feature are using the one-character variable
trick; sometimes enforced by conventions. For example, Go, Rust and Python are using `_` as in :

[_,_,kb] = intersect(grand(1,10,"uin",0,9), grand(1,10,"uin",0,9));

This character appears as a visual blank thus the function call is easily readable.

Regards,
