Trivial C interop - yes. Both pascal and cdecl style calling conventions.
Toolchain? Back then - yes. Today? Probably not; depends what you mean by it. It had perfect COM interop which mattered back then, and you could trivially link stuff if you wanted to. And people did.
Also Wirth had nothing to do with Modula-3, that was all DEC / Olivetti SRC work, done by ex-Xerox people with experience on Cedar and Modula-2+.

Without Pascal there would be no Modula.
I do agree with Modula, which isn't the same as Modula-3.
> most developers never bothered learning the "go to next error" hotkey and just spammed F9 (compile & run) whenever they fixed a syntax error
We didn't know we were privileged. I thought it was normal thing to have.
Ironically it is still easier in Delphi than the frameworks Microsoft keeps pouring out for .NET and C++.
I keep joking they should afford some Embarcadero licenses to learn how to actually do it.
No comptime, but everything else, sure, Turbo Pascal (and then Delphi) had.
Maybe it'll blow your mind (not sure if you find this impressive or not), but Turbo Pascal had sub-second compilation per module on large modules back on my 486 with 4MB of RAM.
Sure, Zig has more features than Pascal, but not the ones you listed (except, of course, for comptime).
And still does. You can get the latest version of Delphi (including a free version for non-commercial use) here: https://www.embarcadero.com/products/delphi
It rocks.
You're also not limited to Delphi. You can use Oxygene https://www.remobjects.com/elements/oxygene/language
If you're not in the mood to rent your compiler, you can also try Lazarus.
Also, for non-commercial use, Delphi is free.
Object Pascal compilers were already super fast in MS-DOS hardware!
