just like unbalanced (), or {}

D:\>perl -e"<>>"
syntax error at -e line 1, at EOF
Execution of -e aborted due to compilation errors.

D:\>perl -e"())"
syntax error at -e line 1, next char )
Execution of -e aborted due to compilation errors.

D:\>perl -e"{}}"
Unmatched right curly bracket at -e line 1, at end of line
syntax error at -e line 1, near "}}"
Execution of -e aborted due to compilation errors.

If you were to change it to

<$$result{fh}>
[download]

it would be equivalent of glob , not readline
