It's just another global used during the compilation of CVs, like
PL_padix, PL_comppad_name, etc etc. At the start of compiling a CV, we
do SAVEI32(PL_cv_has_eval) and set it to 0. During the compile, we set it
to 1 if we discover any eval-like constructs. At the end of compiling the
CV, we check that whether it's got set, and if so, we pessimise any anon
CV's within scope. Thats all.

Nothing ventured, nothing lost.
