Let's say we have a chain of functions.

I would like to have a behaviour in `a()` that would check if
there is `b()` or `c()` chained to it.
If `a();`is not chained: do a `writeln("You forgot to chain
this function!");`
#### A function that executes a program
For me syntactically it is important. One real world
application would be:
`program("someProgramName").pipe("someOtherProgramName");`
Executes and pipes output to another program.
`program();` - Only executes the program.
Consider adding @mustuse on the return type.
