#{NAME} [STRING]

Run code in the context of the current frame.

The value of the expression is stored into a global variable so it
may be used again easily. The name of the global variable is printed
next to the inspect output of the value.

If no string is given we run the string from the current source code
about to be run

#{NAME} 1+2  # 3
#{NAME} @v
#{NAME}      # Run current source-code line
