Add Devel::Declare::Context::Simple and Devel::Declare::MethodInstaller::Simple as an experimental way to make creating block- and sub-like keywords easier (Rhesa Rozendaal).
Changes for version 0.002999_01
Use B::Hooks::OP::Check to register PL_check callbacks.
Use B::Hooks::EndOfScope instead of %^H and Scope::Guard.
Don't segfault if HvNAME(PL_curstash) == NULL.
Don't segfault on 5.9.5+, where PL_parser is a symbol, not a define.
Don't delete the previous symbol table entry when shadowing subs. This makes us work within the debugger.
