(patch for Bash) Python command substitution in Bash

[those who know me have no need of my name]

in comp.unix.shell i read:

>Here is my patch to "command substitution" syntax of Bash to interface

>If command string begins with '!', then the rest of string is sent to

>    python -c "string"

i dislike this appropriation of the special character, especially for so
trivial an invocation.  at the least the character and the program invoked
should be configured, rather than hard-coded.
