A method copies its argument (SPEC), a lambda passes the original today. Should a lambda copy too? My recommendation: copy, as SPEC says; write & for a reference.

Fixed in 4371b7aa (branch tickets6): lambda parameters copy their argument, & makes a reference; interpreter, --native (compile.zig + NativeCompile.hl via hybrids.argsCopied), --js agree. Test tests/pass/basic/050_lambda_copies_argument. Gates: test_interpreter.sh green (packaging 209/0, --native 388/0), test-runner 513/0, native/run/js parity identical.
