Multiple strings as parameter

[sverhoeven]

I would like support for passing multiple string values as a parameter to grlc.

Given SPARQL query like

#+ endpoint: https://sparql.uniprot.org/sparql
PREFIX up: <http://purl.uniprot.org/core/>
PREFIX taxon: <http://purl.uniprot.org/taxonomy/>
SELECT ?protein ?pdb_db
WHERE {
    # --- Protein Selection ---
    VALUES (?ac) { ("O15178") ("O15294")}
    BIND (IRI(CONCAT("http://purl.uniprot.org/uniprot/",?ac)) AS ?protein)
    ?protein a up:Protein .
    ?protein rdfs:seeAlso ?pdb_db .
    ?pdb_db up:database <http://purl.uniprot.org/database/PDB> .
}

To grlc-ify replace ("O15178") ("O15294") with a parameter like (?__uniprotAccessions_stringlist) with possible value ["O15178", "O15294"].

The openapi spec for the parameter would look like

{
    "description": "A list of string values that will substitute ?__uniprotAccessions_stringlist in the original query",
    "in": "query",
    "name": "uniprotAccessions",
    "required": false,
    "type": "array",
    "items": {
        "type": "string"
    }
}

Nice to have if I can specify the minimum and/or maximum number of items in the list.
