Subject: Remove exec() from handle_user_input() function
X-Git-Tag: 0.1.0~18
X-Git-Url: https://mudpy.org/gitweb?a=commitdiff_plain;h=40fb678ab8ea5e35f06826bda8f484053dd831b1;p=mudpy.git

Remove exec() from handle_user_input() function

Stop passing the constructed handler function name into an exec()
and instead reference it from the globals() dict.
