[perl #130673] readline(FH) throws a warning, <FH> does not

A bare word file handle causes the readline(FH) function to emit a warning: Name "main::FH" used only once: possible typo at line 4.

-The equivalent diamond operator <FH> used on the same bare word handle does not evoke the warning.

-Using a lexically scoped file handle with readline( $fh ) also does not evoke the warning.

See attached, thanks
