대응
Write each comment line with /. At the start of an expression, the former / opener produces TPZ2001 during parsing.
Historical compiler facts for the reserved code. These facts describe the former diagnostic, not a 6.0.0 trigger.
Compiler phase: lex.
Compiler explanation: A block comment reached the end of input before its closing delimiter.

Observed for the candidate in Topaz 5.21.3. Execution
- error[TPZ0002]: unterminated block comment
TPZ0002 is retired in Topaz 6.0.0 and remains reserved for its former meaning, an unterminated block comment. It must not be emitted or assigned a new meaning.
Reserved code and current rejection
TPZ0002 is retired in Topaz 6.0.0. Its code and former meaning remain reserved and must not be reused. Source comments begin with /. Outside a string or line comment, / supplies the ordinary / and * tokens. At the start of a statement or expression, this sequence produces TPZ2001 in the parse phase. Adding a closing */ does not make it a comment. Whitespace between / and * does not give the sequence a comment meaning.
이유
One comment spelling makes ignored source text unambiguous. The line-comments-only decision selects /. A retired code keeps its old meaning so stored diagnostics and links remain understandable. Invalid expression tokens use the existing parse diagnostic, which also applies when whitespace separates them.
Response
링크Write each comment line with /. At the start of an expression, the former / opener produces TPZ2001 during parsing.
