That caused fatal errors by virtue of S_* constants being barewords. They are not recognized as subs during the compile time (since above happens outside of BEGIN), thus cause the "bareword" error.

Add () and one is back in business ...

If you want the routines imported at compile time, why do you want to use require+`import`? Perl has use to import symbols at compile time for just that reason.	[reply] [d/l]

I am aware of that; I did not want to import at compile time, only during run time. A constant, rather a usable sub without parentheses, it is not then when one goes from the document using `use` to code using `require`. OTOH, object reference use is just dandy of course. This is also a reminder to self yet again about constant\|function-call-with-optional-parentheses usage.	[reply] [d/l] [select]
