This line attempts to set $0 to the substitution of a regular expression, it takes $_ as an argument and replaces the value matched by a regular expression .*/ with an empty string. I don't pretend to understand the error message, it just seems to me that $0 is the implicit variable that contains the entire string when using regular expressions ($1... and so on are subsequent matches) and that $0 in that context might be read only.
