`purescript-ref` doesn't compile due to foreign exports mismatching format

[Renegatto]

On the one side it does expect that, on the other side it does not wrap their exports in the parentheses, violating it's own expectations.

[info] Build succeeded.
PS Lua: compiling ...
Linker error:

Wrapping value in the parentheses would indeed work:

   _new = (function(val) return function() return {value = val} end end),

It seems to be right there:

purescript-lua/lib/Language/PureScript/Backend/Lua/Linker/Foreign.hs

Lines 95 to 96 in bef2ba6

	foreignExport ∷ Parser (Key, Text)
	foreignExport = do

[Renegatto]

It does not really misexpect this:

purescript-lua/lib/Language/PureScript/Backend/Lua/Linker/Foreign.hs

Line 46 in bef2ba6

The <value> is a Lua expression. The braces around a <value> are required.

That probably means that the dependency (in this case Ref library) foreign code should be fixed.

The foreign code in the purescript-lua-ref has been fixed, please update your package set and close this issue if the problem is gone, thanks!
