Lost type of variable

[lulco]

Plugin lost type of variable when it is used in function:

{varType FooBar[] $fooBars}

{foreach $fooBars as $fooBar}
    {$fooBar->doSomething()} // everything ok
{/foreach}

{foreach array_slice($fooBars, 0, 4) as $fooBar}
    {$fooBar->doSomething()} // lost type of $fooBar (should be FooBar)
{/foreach}

There are several functions like this, maybe plugin can get inspiration in phpstan
