It's still reading the block signature (parameters and return type) that it
expects after the ->, until it sees the start of the block/closure.
Think of what follows it as a sub declaration without the sub name or
parentheses. A semicolon there says that what follows are optional
parameters, so it's expecting either a parameter name, or a type to give to
the following parameter name.
