Have a code:

class MyClass{
    private $field;
}

Select, for example, three letters "las" in the editor. Result: on the left, a lamp appears. After clicking it, the IDE
offers to surround this part of code with try{ block. It's wrong, because it makes no sense in this context.

It happens for many other cases, but it doesn't happen somewhere: for example, if you select letters in a field
definition (like "riv" in the example above), no lamp appears. So it seems that editor tries to detect when this action
should be offered, but does it wrong.
