In that case there might be a simpler solution: The global
PANDOC_WRITER_OPTIONS became available in pandoc 2.17. With that you can
access variables in writers by indexing
`PANDOC_WRITER_OPTIONS.variables`.

To give a short example: if you call pandoc with

pandoc --lua-filter=var-test.lua --variable foo=hello <<< ''

where `var-test.lua` contains

print(PANDOC_WRITER_OPTIONS.variables.foo)

then you'll get `hello` printed to the terminal.
