I publish games.  I care about performance.  I am willing to sacrifice 
some performance by using a scripting language, but when a construct can 
be created that enhances performance over the alternative, like a switch 
statement over a table of functions, I am for it.

The Lua C source code itself uses switch in dozens of places.  The 
result is plenty readable and arguably far more readable than a table of 
functions that have to be defined elsewhere in the file.
