[Python-ideas] String interpolation: environment variables, command substitution

[Mike Miller]

Hi,

The use case is for shell-script replacements, which can be but are often not 
typically cross-platform.   Let's try different examples:

     >>> x'version: {$(/usr/bin/xdpyinfo -version)}'  # capture
     'version: xdpyinfo 1.3.1'

     >>> x'display: {$DISPLAY}'                       # env
     'display: :0.0'
