This all makes sense to me, but given the constraint of statically defined methods, would it be reasonable to have the linter locate method names in known namespaces or else give warning? For method invocations on references where the class cannot be known at compile time, this would at least catch the 'method doesn't exist anywhere in a known namespace' type of error. I understand that this is not useful in the general case, but with 100K lines of code strewn over 200 files and classes with fairly verbose method names it sure would be nice to know that 
$dataView->htmTable('edit');

will fail when the method is actually called 
sub htmlTable { }

[download]
When $dataView's class cannot be known, having 'htmlTable' exist somewhere in the application namespace is clearly no guarantee of success at runtime... but missing the 'htmTable' bug is a *definite* guarantee that there will be a problem. A lint check, imperfect as it may be, still seems to offer value in my case.
