table construction: key is string with dash

[Christopher Kappe <nox_diesque@...>]

Hello all,

I don't know if this has been discussed before or if the question is too 
silly but I couldn't find anything on the topic by searching google and 
the mailing list archive.

Concerning the construction of tables, I was under the assumption that
{ foo = bar } -- where foo is a string and bar is some variable
is the same as
{ ["foo"] = bar }
But - and that's the point of my email -
{ foo-fighter = bar }
gives an error ('}' expected near '=').

Probably the interpreter thinks that dash here is a minus operator and 
so foo and fighter must be number variables with a likewise numerical 
result of the subtraction and thus the "key-is-a-string" syntactic sugar 
doesn't apply. But this wouldn't happen, if the "=" sign was processed 
first (?).

I bring this up because I really much would like to use such syntax. The 
background is that I like to create svg images with Lua scripts. This is 
easier, quicker and yields better results for me than struggling with 
programs like Inkscape, Draw or Dia. Especially the set of attributes 
for a svg tag is perfectly reflected by Lua tables. E.g. I can make a 
function call as
svg.rectangle{ width=100, height=42, fill="black" }
But attributes with a dash require the ugly syntax
svg.rectangle{ fill="black", ["stroke-width"]=1.337 }

So I wonder what you think. Could this kind of syntax be allowed in any 
later version of the language?

Best regards,
