Because that's fundamentally incompatible with a competently-designed compiled language. Consider:

  fn immutable foo() long:
    asm(long x:"rax") "mov rax 7"
    return x

Now try cross-compiling that from a 32-bit ARM machine.

Aside: D is kind of weird in this regard because most of it is designed to work as a interpreted language as well as a compiled one. To the extent the D is good, it's not compiled[0]; to extent that it's compiled[0], it's not good.

0: in the language design sense, not the language implementation sense.

Pretty much all languages with turing-complete compile-time expressions only expose a subset. This comfortably lands in the "not in that subset" category.

If you only expose a subset, you very specifically don't have the full use of the programming language.

Now you're just being pedantic. Also, leaving out the "D" just before your quote is plain disingenuous. That contextualizes the discussion and clearly establishes we don't mean being able to directly run ASM operations and syscalls willy-nilly at compile time.
