[PATCH] Add new_from_string() to LuaNumber (was: Re: .const & HLL improvement)

[Klaas-Jan Stol]

    .const .LuaNumber n = "12.34"

I presume LuaNumber doesn't have new_from_string (Float hasn't either).

Attached is a patch that implements new_from_string() for LuaNumber.
In my opinion it's handy to say:

    .const .LuaNumber n = "12.34"

kind regards,

klaas-jan
