I guess I am doing somehthing wrong, but I can't find what.

When compiling this code with Perl version 5.8.8:

$ cat Prueba3.pm
  BEGIN {
    unless (Parse::Eyapp::Driver->can('YYParse')) {
      eval q{

package Parse::Eyapp::Driver;

require 5.006;

#sub _DBLoad {

1;


      }; # End of string containing Parse::Eyapp::Driver
    }; # Unless Parse::Eyapp::Driver was loaded
  } ########### End of BEGIN
[download]

it gives me an error:

$ perl -c Prueba3.pm
Missing right curly or square bracket at Prueba3.pm line 16, at end of
+ line
  (Might be a runaway multi-line {} string starting on line 3)
syntax error at Prueba3.pm line 16, at EOF
Prueba3.pm had compilation errors.
$ perl -v
This is perl, v5.8.8 built for i486-linux-gnu-thread-multi
[download]

If I delete the comment there are no errors:

pl@nereida:/tmp$ diff Prueba3.pm Prueba.pm
9d8
< #sub _DBLoad {
pl@nereida:/tmp$ perl -c Prueba.pm
Prueba.pm syntax OK
[download]

Can someone help?

Thanks

UPDATE:

I have got the same behavior when using Perl 5.10.0

casiano@beowulf:~$ perl -v
This is perl, v5.10.0 built for i486-linux-gnu-thread-multi

casiano@beowulf:~$ perl -c Prueba3.pm
Missing right curly or square bracket at Prueba3.pm line 16, 
at end of line (Might be a runaway multi-line {} string starting on li
+ne 3)
syntax error at Prueba3.pm line 16, at EOF
Prueba3.pm had compilation errors.
casiano@beowulf:~$ perl -c Prueba.pm
Prueba.pm syntax OK
casiano@beowulf:~$ cat -n Prueba.pm
     1    BEGIN {
     2      unless (Parse::Eyapp::Driver->can('YYParse')) {
     3        eval q{
     4
     5  package Parse::Eyapp::Driver;
     6
     7  require 5.006;
     8
     9
    10  1;
    11
    12
    13        }; # End of string containing Parse::Eyapp::Driver
    14      }; # Unless Parse::Eyapp::Driver was loaded
    15    } ########### End of BEGIN
casiano@beowulf:~$ cat -n Prueba3.pm
     1    BEGIN {
     2      unless (Parse::Eyapp::Driver->can('YYParse')) {
     3        eval q{
     4
     5  package Parse::Eyapp::Driver;
     6
     7  require 5.006;
     8
     9  #sub _DBLoad {
    10
    11  1;
    12
    13
    14        }; # End of string containing Parse::Eyapp::Driver
    15      }; # Unless Parse::Eyapp::Driver was loaded

Of course, the problem can be "solved" by inserting a false "}" inside a comment:

$ perl -c Prueba3trick.pm
Prueba3trick.pm syntax OK
pl@nereida:/tmp$ cat -n Prueba3trick.pm
     1    BEGIN {
     2      unless (Parse::Eyapp::Driver->can('YYParse')) {
     3        eval q{
     4
     5  package Parse::Eyapp::Driver;
     6
     7  require 5.006;
     8
     9  #sub _DBLoad { # False curly: }
    10
    11  1;
    12
    13
    14        }; # End of string 
    15      }; # Unless Parse::Eyapp::Driver was loaded
    16    } ########### End of BEGIN
