Hi: I'm not sure if this issue resides with Neo4j or Cycli; I suspect the latter (Cycli), as detailed below.
Problem Description
I prefer to use cypher scripts and Neovim, rather than the Neo4j Browser, for working with data.
However, when I comment-out ( // ... ) lines in the cypher scripts using a keyboard shortcut in Neovim, commented lines lines ending in semicolons throw warnings in Cycli.
The same code pasted into the Neo4j Browser, or the same script loaded into Neo4j via cypher-shell results in reading of the code, with no wrnings.
Thus, when I am writing scripts and and I want to comment out statements that end in a semicolon with my keyboard shortcut (Neovim editor), I ALSO need to go to the end of all of those //-commented lines and delete those semicolons (reversing that tedious process when uncommenting those lines).
That is, if I want to avoid seeing those warnings.
glycolysis_bioentities.csv
[exported form a PostgreSQL database, hence the .csv extension]:
LOAD CSV WITH HEADERS FROM "file:/glycolysis_bioentities.csv" AS row
MERGE (n:Glycolysis {name:row.name})
// RETURN n, labels(n), n.name;
RETURN n.name;
// Same:
// MATCH (n) RETURN n.name;
Examples - Cycli :
cycli -P 7474 -u victoria -p <password_obfuscated_here> -f glycolysis.cypher
> LOAD CSV WITH HEADERS FROM "/glycolysis_bioentities.csv" AS row
MERGE (n:Glycolysis {name:row.name})
// RETURN n, labels(n), n.name;
109 ms
> RETURN n.name;
Variable `n` not defined (line 1, column 8 (offset: 7))
"RETURN n.name;"
^
> // Same:
// MATCH (n) RETURN n.name;
Unexpected end of input: expected whitespace, comment, CYPHER options, EXPLAIN, PROFILE or Query (line 2, column 29 (offset: 37))
"// MATCH (n) RETURN n.name;"
^
(py35) [victoria@victoria Vancouver]$
Despite those warnings, the 22 nodes are created in the Neo4j Browser. So it appears to be a warnings-related issue, not a script execution errors.
Compare that shell output to this modified script, where I deleted semicolons at ends of //-commented lines:
LOAD CSV WITH HEADERS FROM "file:/glycolysis_bioentities.csv" AS row
MERGE (n:Glycolysis {name:row.name})
// RETURN n, labels(n), n.name
RETURN n.name;
// Same
// MATCH (n) RETURN n.name
Script execution - Cycli :
cycli -P 7474 -u victoria -p <password_obfuscated_here> -f glycolysis.cypher
> LOAD CSV WITH HEADERS FROM "file:/glycolysis_bioentities.csv" AS row
MERGE (n:Glycolysis {name:row.name})
// RETURN n, labels(n), n.name
RETURN n.name;

As mentioned, this does not occur when loading that same .cypher script into cypher-shell, where it runs without issue (resulting in 22 nodes in the Neo4j Browser):
