Semicolon in or after a variable

variable.suspiciousSemicolon

Message

Variable '<name>' contains or is immediately followed by ';', which starts a comment in many MeTTa parsers; the rest of the line is ignored.

What it means

A ; sits inside or directly after a variable with no space. In many MeTTa parsers ; starts a line comment, so everything after it on that line, often the closing ), is silently dropped. The code you see may not be the code that runs.

Why it happens

A comment written with no space after a variable ($x;note), or a ; typed where a different separator was meant.

How to fix it

Put a space before the comment, or remove the ;.

(foo $x;note)    ; ';note)' is a comment — the ')' never closes 'foo'
(foo $x ;note)   ; a space makes it explicit and keeps the ')'

This is a hint, always reported. To silence one occurrence, add ; @suppress variable.suspiciousSemicolon on the line above it.
