"bring" ===String[bring]

False

Cases[{"bring"}, _String]

{bring}

Cases[String[bring], _String]

{}

Cases[ToString[bring], _String]

{}

InputForm[String[bring]]

String[bring]

InputForm["bring"]

"bring"

FullForm[String[bring]]

String[bring]

And yet:

Head["bring"]

String

FullForm["bring"]

"bring"

ToString[bring]

bring

InputForm[%]

"bring"

Wha????

Thanks,

Kris
