Is this really?
perl -E 'sub substr { print "substr\n" }; substr();'
Output
Not enough arguments for substr at -e line 1, near "substr()"
Execution of -e aborted due to compilation errors.
Imported symbols don't seem to override CORE::substr,
Although the following is OK.
perl -E 'sub substr { print "substr\n" }; &substr();'
Output
substr
