nums

This is a basic cli calculator that uses postfix notation and can accept piped data. To use data from a command line pipe use the -p flag, for example: echo "2 2 +" | nums -p. The example would output 4, but without the -p flag would produce a runtime panic.

For help/available operators enter ? or help at the repl or via piped data to get help information printed to stderr.
