I'll admit, though, that I really wanted to italicize at least one syntax group, and although it's possible to minimally override a colorscheme in this way, any implementation is error prone, possibly version-dependent, and hard to understand and maintain (as is much of Vimscript). replaces the name with its value; this is called "variable interpolation". Type checking and type information lookup. To make this possible it needs to know the syntax state at the position where redrawing starts. by a "magic" backslash in front of them.
