As fast as the dmd one would be best.
That'd be great but . . .
lexer really isn't the performance bottleneck of dmd (or any compiler of a non
trivial language). Additionally, anybody that have touched dmd source code can
agree that usability/maintainability isn't as its best.
Sacrificing some perfs in a non bottleneck area to increase ease of use make
perfect sense.
A lexer is like a device driver, or a memory allocator. Having it be as fast as
possible pays off dividends endlessly for whoever uses it.
And in my profiling, lexing speed is a big factor in the debug build times.
The Digital Mars C++ compiler (and its antecedents) made a lot of hay by being
the fastest compiler available by a wide margin. A big advantage D has is also
compile speed.
Please do not underestimate its importance.
