What can I do while maintaining a Style?

[Zepha]

Can a spellcaster enter and maintain a style while spellcasting? For example, can a wizard with the Snake Style feat begin the style and cast a spell in that and subsequent rounds while still getting the benefit of the style feat?

Basically, it's a swift action to enter a style, and then it's on until you end it. Nothing else required.
