Hi All,
For the fun of it, I placed a "booboo;"
in the BEGIN block to see what the syntax
checker would do:
$ raku -c GetUpdates.pl6
===SORRY!=== Error while compiling /home/linuxutil/GetUpdates.pl6
Undeclared routine:
booboo used at line 28
Caught it. No BEGIN pop up
Then I moved the booboo to the end of the
program
$ raku -c GetUpdates.pl6
===SORRY!=== Error while compiling /home/linuxutil/GetUpdates.pl6
Undeclared routine:
booboo used at line 11664
Caught it. And I also got the BEGIN's pop up.
Interesting!
:-)
