No. Syntax highlighting is done by the lexer, no (complex) parsing

Syntax highlighting needs to be rather fast, as it is done during
drawing, so switching context is out of the question. Instead, Visual
D keeps a lexer-state (an int) per line and continues scanning from
the start of the line when color information is requested by the IDE.
I couldn't find respective code so far
It's mostly in class Colorizer, with the IDE paint callback being
ColorizeLine.
