_a(arg)
- Extracts the argument from the common ways mediawiki passes arguments to modules:

argis a table and that table has aargsfield,arg.args[1]is returned (Called from MediaWiki’s {{#invoke:}} parser function) - if
argis a table but doesn’t contain anargsfield,args[1]is returned (Called with a table as an argument list[1])
