op-comment	Comment	operators	operator		Everything after	9

A comment begins with # and runs to the end of the line; the compiler ignores everything after it. Ludic has only this one line-comment form — there is no block-comment syntax — so to comment out several lines put a # on each. Use comments to explain intent next to a const, to label a section of a handler, or to note a gotcha. The source formatter (ludic-fmt) works on tokens, so your comments and blank lines survive a reformat.

let score: int = 0                 # reset in the Start phase
