Opcode names are not reserved words in PIR, and may be used as variable names.
For example, you can define a local variable named C<print>. [See RT #24251]
+PIR keywords, on the other hand, I<are> reserved, and cannot be used as
+identifiers. Some opcode names (C<if>, C<unless>) are, in fact, PIR keywords,
+which therefore cannot be used as identifiers.

{{ NOTE: The use of C<::> in identifiers is deprecated. [See RT #48735] }}
