Is it possible to pass a dummy parameter to a user-defined operator,

The following test program compiles OK but fails at runtime with an
error 217 on all platforms if the record is empty. It works if it
contains a variant, but not reliably with other types.
It seems that the compiler does not detect here that the variants unit
is needed and thus does not implicitely add it. Please open a bug report
with your code as an example. As a workaround simply add the unit
"variants" to the unit where your operator is defined.
Btw: You don't need the "s: Variant" for operators in mode Delphi or
mode ObjFPC as there you can use "Result" as usual (just write ":
Variant" as for normal functions).
