'Unable to parse module: ErrorMessage { msg: "ParserError: Invalid token at 144" }

Move
#1

I successfully started a local swarm with 4 nodes all good there, now I am trying to compile the following example:

module MyModule {
 import 0x0.LibraCoin;

 // The identity function for coins: takes a LibraCoin.T as input and hands it back
 public id(c: R#LibraCoin.T): R#LibraCoin.T {
   return move(c);
 }
}

But I am getting the following error:
Unable to parse module: ErrorMessage { msg: "ParserError: Invalid token at 144" }

If I remove both “R#” occurrences it does compile successfully. Any idea why it’s not accepting R#?

Thanks!! :+1:

Hi Juan,

We made kind annotations (R#/V#) optional in #472, and removed them in #539 to make the IR syntax less verbose. The compiler will now look up the struct definition and determine the kind for you.

Oh that’s even better, thanks for your prompt reply @vgao :+1:
