A way to write switch-case statements in lua.
print "Hello, switch"
-- If the default case does not have to be handled, we can use the following auxiliary function:
local function switch(value)
-- Handing `cases` to the returned function allows the `switch()` function to be used with a syntax closer to c code (see the example below).
-- This is because lua allows the parentheses around a table type argument to be omitted if it is the only argument.
return function(cases)
-- The default case is achieved through the metatable mechanism of lua tables (the `__index` operation).
setmetatable(cases, cases)
