Those syntaxes are saying two separate things.
$Request->Form('test')->Item() calls the method `Form' on the object
`$Request' with argument `test', and calls the method `Item' with no
arguments on the result.
$Request->Form->('test')->Item() calls the method `Form' on the object
`$Request' with no arguments, and calls the return value as a subroutine
with argument `test'. Thus, if `Form' doesn't return a coderef, it will
crash and burn.
