Do GScanner symbols have to be identifiers?

[Florian Pelz <pelzflorian googlemail com>]

Hello,

I'm trying to parse code using GLib's GScanner. I added a symbol ":=", 
but it is not reported as a G_TOKEN_SYMBOL but instead as G_TOKEN_CHARs. 
> From looking at GLib's source code, it seems to me that only identifiers 
can be symbols, and since ":=" contains characters that may not appear 
in identifiers as I defined them, ":=" is not reported as a symbol when 
parsing.

Am I correct in that symbols have to be well-formed identifiers to be 
reported as a G_TOKEN_SYMBOL? This does not become clear from the GLib 
documentation. Should I open a bug report for this? Is parsing the 
G_TOKEN_CHARs ":" and "=" the proper way to recognize a := operator?
