[Linker <linker.m.lin@...>]

But "local f; f " make 'f' be a global variable.

from the manual:
2.5.9 - Function Definitions

.....snip...
The statement
    local function f () body end

 translates to
    local f; f = function () body end

not to
    local f = function () body end

 (This only makes a difference when the body of the function contains
references to f.)
