docs: fix bare reassignment examples to match compiler behavior#1
Merged
Conversation
Bare identifier reassignment (`y be 20`) is not supported (RFC 6.4) and is now reported as a compile error (puruslang/purus#8), but several examples still used it — those examples silently dropped the assignment (the while loops would infinite-loop): - reference/operators: remove `y be 20` from Assignment; add a caution pointing to property/index/destructuring targets and compound assignment - reference/control-flow: while example `i be i add 1` -> `i add be 1` - reference/functions: generator example `i be i add 1` -> `i add be 1` - getting-started/hello-world: `y be 100` -> `y add be 1` The for-loop update clause (`for let i be 0; i lt 5; i be i add 1`) is special-cased by the parser and remains valid, so those examples are unchanged. Both en and ja pages updated.

Summary
Bare identifier reassignment (
y be 20) is not supported per the RFC (6.4 Assignment) and becomes a compile error with puruslang/purus#8 — but several docs examples still used it. Until now those examples silently dropped the assignment at compile time (the while-loop examples actually infinite-looped when run).Changes (en + ja)
