Re: Reducing memory consumption

[Mark Hamburg <mhamburg@...>]

Somewhat less successful at the immediate poof, but:

    local funcs = gimme_funcs() -- returns a table by name
    local func1 = funcs.func1
    local func2 = funcs.func2
    etc.
    func = nil

For a balance of speed v space, cache the results of gimme_funcs via a weak
table. In other words:

    local gimme_funcs_cache = setmetatable( {}, { __mode = "kv" } )

    function gimme_funcs()
        local funcs = gimme_funcs_cache[ 1 ]
        if not funcs then
            funcs = real_gimme_funcs()
            gimme_funcs_cache[ 1 ] = funcs
        end
        return funcs
    end
