Yes, it makes sense from this perspective, but from a real-life
programming perspective it is
1) useless - count() provides no useful information about strings
2) potentially buggy.
For instance, PEAR's XML_Unserializer (XML_Serializer package)
represents XML elements with simple text node children as a string, and
tags with anything else (attributes, child elements) as an array.
Improperly written code that uses count() without checking is_array()
would happily run with no warning whatsoever. However, imho it would
make PHP more robust if the logical error condition were also a language
error, that's all.
