digitalmars.D.learn - SDL Error: identifier expected following '.', not 'version'

Hello,
whenever I try to compile this chunk of code:

[code]
SDL_SysWMinfo info;
SDL_VERSION(&info.version);
if(SDL_GetWindowWMInfo(win,&info)) {
   writeln(info.subsystem);
}
[/code]
  this error shows up:
  Error: identifier expected following '.', not 'version'



BTW, i'm following the SDL official documentation (written for 
C): https://wiki.libsdl.org/SDL_GetWindowWMInfo
   Derelict SDL is fine, I have compiled SDL code before.
I Know that the word "version" is reserved for D, but how do I 
circumvent this issue?

Use the source, Luke! [1]

Because, as you say, version is a keyword, it will not compile 
when used as an identifier. As such, Derelict cannot use it, so 
you don't need to circumvent the issue since DerelictSDL2 already 
has done it for you. You just need to use the correct identifier:

SDL_VERSION(&info.version_);

When using Derelict, in any circumstance where you run into an 
identifier from a C library that is the same as a D keyword, just 
append an underscore to it. It's possible there may be remnants 
of older versions of Derelict where I didn't adhere to that 
pattern. If you ever encounter such, please file an issue. I want 
to be consistent with this.

BTW, I should caution that the Sys_WM stuff in Derelict may be 
buggy. If you run into any odd behavior, feel free to blame it on 
Derelict (as long as you report it!).
