<?hh //strict
foreach ($list as $id) {
$items = new DestinationsByCountry($id);
$remapped = $items->byKey('destination_id')->map($stringed ==> (int) $stringed);
$this->ids->addAll($remapped);

}
对于类型检查者来说两者都可以,但第二个导致致命错误
致命错误:语法错误,意外T_OBJECT_OPERATOR,期待')'

正如上面的评论中所指出的,你需要在body.products table {
table-layout: fixed;
}
body.products table tr:first-child > td {
width:50%;
}
body.products input.add[type="button"] {
color: white;
width: 100%;
background-color: #27af60;
border: none;
letter-spacing: .8px;
}
body.products input.del[type="button"] {
color: white;
width: 100%;
background-color: #c0392b;
border: none;
letter-spacing: .8px;
}
body.products input.submit[type="submit"] {
color: white;
width: 100%;
background-color: gray;
border: none;
letter-spacing: .8px;
}
周围使用括号,包括PHP和Hack语法。
typechecker没有抱怨的原因是因为it doesn't typecheck code at toplevel。如果这是在一个函数或方法中,我希望typechecker会发现错误。如果此代码实际上在函数或方法中,请执行file an issue on GitHub。
