Nothing << Thing -- dummy file output

Nothing << Thing -- dummy file output

Synopsis:

Operator: <<

Input:

an instance of class Nothing.

an instance of class Thing.

null << x -- does nothing and returns null.

The intention here is that you can use null as a dummy output file, but a bit of time is wasted converting x to a net.

Code:

     -- ../../../Macaulay2/m2/document.m2:320
     Nothing << Thing := (x,y) -> null                           -- turning off the output is easy to do
