Haha, yeah, I still forget about this sometimes and instinctively wrap string variables in quotation marks. Sometimes I wish C3 was stricter about this, more like traditional programming languages.
On the other hand, this lets you store entire JSON strings in variables without needing to escape every quotation mark.
For example:
Text variable myJSON = {"name":"John", "age":30, "car":0}
Instead of:
Text variable myJSON = "{"""name""":"""John", """age""":30, """car""":0}"
