How to make code GC-Safe when a global constant is used in a proc ?

[jbcomps]

Looks like the code is missing a closing `.` for the pragma on line 36.

`proc prepareFirstMessage*(s: ScramClient, username: string): string {.raises: 
[ScramError].} =`

vs

`proc prepareFirstMessage*(s: ScramClient, username: string): string {.raises: 
[ScramError]} =`
