56 | The following modules will be removed from the core distribution in a |
57 | future release, and will at that time need to be installed from CPAN. | |
58 | Distributions on CPAN which require these modules will need to list them as | |
59 | prerequisites. | |
eabfc7bc | 60 | |
cf73ceda MH |
61 | The core versions of these modules will now issue C<"deprecated">-category |
62 | warnings to alert you to this fact. To silence these deprecation warnings, | |
63 | install the modules in question from CPAN. | |
26230909 | 64 | |
cf73ceda MH |
65 | Note that these are (with rare exceptions) fine modules that you are encouraged |
66 | to continue to use. Their disinclusion from core primarily hinges on their | |
67 | necessity to bootstrapping a fully functional, CPAN-capable Perl installation, | |
68 | not usually on concerns over their design. | |

92 | Creating Perl debugger data structures (see L<perldebguts/"Debugger Internals">) |
93 | for XSUBs and const subs has been removed. This removed one glob/scalar combo | |
94 | for each unique C<.c> file that XSUBs and const subs came from. On startup | |
95 | (C<perl -e"0">) about half a dozen glob/scalar debugger combos were created. | |
96 | Loading XS modules created more glob/scalar combos. These things were created | |
97 | regardless if the perl debugger was being used or not, unlike for pure perl | |
98 | subs, and ignores that the perl debugger can not debug C code. | |
