There is also the "set" shell command, i e "set audio.driver alsa" 
instead of your "a = b" syntax.

The problem is though that some things should be set before creating the 
synth (and other objects), such as which audio driver to use, and other 
things need to be done afterwards, such as which soundfonts to load.

Btw, looking at the code, the fluidsynth executable also seems to 
automatically run shell commands from ~/.fluidsynth and 
/etc/fluidsynth.conf. (The fluid_get_sysconf and fluid_get_userconf 
commands can be used to get these filenames.)
