The nil check burn down added guards which turned out redundant once
the surrounding annotations landed. `_has_handlers` is set to true when
the first handler registers, so it is a boolean rather than the literal
false it was inferred as.

`assert` returns every argument it is given, so `return assert(x, msg)`
was leaking the message as a second return value.
`get_tile` is documented as taking x and y. The async function class
declared `@operator call` with no parameters, which made every async
call look over supplied.

Guards now cover the statements that follow them, and a couple of reads
are restructured so the narrowing survives.
