text_buffer <-scan_syntax: from=[int],
to=[int] -> tupleFind syntactical state of position using the defined string and comment
syntax from the associated text_buffer<-syntax

outside comment and strings. The return-value is a tuple
object, whose first part is a name indicating the syntactical category
at to and whose second part denotes the start-position of
this syntactical object.
Returned syntactical categories:
- code
- To is outside strings or comment
- comment
- To is inside a comment
- string
- To is inside a quoted string.
