in reply to Creating wrapper over a wrapper

Try 

use ABC ();

i.e., don't import the original functions into your PQR namespace, if you're going to define wrapper functions of the same name.

(When writing just "use ABC;" the functions are automatically imported because they are in the @EXPORT array (as opposed to @EXPORT_OK) — see Exporter.)

    This also doesn't work. I still get errors.
    Too many arguments for ABC::new_time_var at /u/agarwsun/projects/packages/datelib/lib/perl5/5.8.6/i86pc-solaris/ABC.pm line 71, near "@_)"

    Not enough arguments for ABC::dl_ascii_to_time at /u/agarwsun/projects/packages/datelib/lib/perl5/5.8.6/i86pc-solaris/Deshaw/ABC.pm line 81, near "@_)"

    Not enough arguments for ABC::dl_compare at /u/agarwsun/projects/packages/datelib/lib/perl5/5.8.6/i86pc-solaris/Deshaw/ABC.pm line 91, near "@_)"

    The actual signatures of these subroutines are: 
    <new_time_var>() 
<dl_ascii_to_date>(<string>) 
<dl_ascii_to_time>(<string>, <dtp>)

      Well, if the ABC::new_time_var function is declared with a prototype of (), meaning no arguments, you cannot call it with arguments in your wrapper, like ABC::new_time_var(@_).  Similarly for the other two functions.

      See also other threads on using prototypes here, to better understand how prototypes work in Perl (hint: they don't act like in C).

        But how come then passing @_regardless the number of arguments function expects, works fine in case we write a wrapper over a pure perl module?
