Thoughts on optional commas

[Greg <tghill@...>]

Occasionally I forget commas when I create large nested tables in Lua.  It
reminds me of when I was learning c and always forgetting to place semicolons at
the end of a line.  I'm so happy that semicolons are optional in Lua.  I wish
commas were too.

Could this work?

Example:

local node= {
    {template="window"
        {template="rect" x=10 y=100 alpha=1
            
            s1 = {color="red"}
            s2 = {color="blue" x="=x+1"}
            s3 = {color="blue" x=10}

        }
        {template="textbox" }
    }
}

Instead of traditionally:

local node= {
    {template="window",
        {template="rect", x=10, y=100, alpha=1,
            
            s1 = {color="red",},
            s2 = {color="blue", x="=x+1",},
            s3 = {color="blue", x=10,},
        

        },
        {template="textbox", },
    },
}

I always end up using trailing commas in my tables and it feels wasteful. 

Any thoughts?
