in thread Sub ref from string without eval

It is only implicit usage of strings as references that is prohibted by strict refs.

Nope.

$ perl -e'use strict; my $x = "foo"; \${ $x }'
Can't use string ("foo") as a SCALAR ref while "strict refs" in use at
+ -e line 1.

$ perl -e'use strict; \${ "foo" }'
Can't use string ("foo") as a SCALAR ref while "strict refs" in use at
+ -e line 1.
