AI Summary: This issue proposes adding an EOF (End Of File) terminator to the start rule of the Expr.g4 grammar. This change aims to ensure that ANTLR parses the entire input and reports all errors, rather than stopping at the first valid parse and potentially ignoring subsequent errors, a behavior introduced in ANTLR 4.7.

Complexity: 2/5
