According to the spec, "If applied to an expression, it is the source
representation of that expression. Semantic analysis is not done for that
expression."

But it seems that semantic analysis always occurs. This does not compile:
---
const char [] q = (1.2143*nonexistent).stringof;
---
By contrast, is() expressions also don't do semantic analysis, and they work
correctly:
static assert(!is(typeof(1.2143*nonexistent)));
