It is not one line because it needs a bit of setup (and teardown, 
but the objects' destructors do that for you) but it is close:

`input.getch` waits for a single line, but you can use 
`if(input.kbhit())` to see if it would block before calling it.

Better be careful, the mods are out in force deleting posts this 
week that tell the hard truth. But yeah, the stdlib in D has very 
little activity:

So you can't expect much from it. My arsd libs provide a broad 
set of functionality missing from it: stuff like this 
terminal/console stuff, window creation, basic guis, web servers, 
etc.

If you want to try them, you can use it from the dub system, but 
I recommend just `git clone 
https://github.com/adamdruppe/arsd.git` in your working directory 
then import what you want and use `dmd -i` to automatically 
include them in the build.
