Syntax issue when chaining tokens

[MatteoPiovanelli-Laser]

Laser.Orchard.Platform/src/Modules/Laser.Orchard.StartupConfig/Tokens/ParameterToken.cs

Line 83 in b4e9f6f

chainIndex = token.IndexOf(").") + 1;

Example: {Content.Parameter:TitlePart-Title).Slug}
This syntax is not very clear, because the parenthesis has not been opened in the token anywhere. Also, it may clash with some tokens that take their parameters in parenthesis.

I am not sure whether this issue is in every other definition of tokens. It may be worse if it isn't, because a fix would likely be breaking for existing configurations.
