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

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
