And why would you say so?

When specifying a font via file name, you always get a single file, 
which typically(*) contains just one single font face; e.g. `arial.ttf` 
would give you the Arial Regular font face, while `arialbd.ttf` would 
give you the Arial Bold font face. So `text { ttf "arial.ttf" bold ... 
}" would make no sense.

When specifying a font via font name, you actually name the font family, 
e.g. "Arial", and have to provide additional information to select which 
font face of the family you want to load.


(*)As far as /font collections/ are concerned, i.e. files which contain 
multiple fonts, I'll still have to do some research to figure out what 
that even means and how they work. If it turns out that selectors like 
`bold` and/or `italic` are useful for font collections as well, the 
syntax for filename-referenced fonts will be extended accordingly. But 
not now.


As for /faux bold/ fonts - i.e. bold-looking fonts synthesized "on the 
fly" using mathematical transformations, rather than having been 
separately constructed by a font designer - if I implement such a 
feature I'll probably provide a separate syntax for it, to give the user 
full contropl over the magnitude of the effect. Such syntax would be 
available independent of the font source, so you could e.g. reference 
the bold variant of a system font and synthesize an even bolder font 
from it.

As for /faux italic/ (which is actually a misnomer, since such a font 
would be an oblique rather than italic font) such an effect can already 
be achieved using a shearing transformation on the resulting object.
