Dots in parameter name

[Kemyke]

Hello,

I am trying to migrate from v0.38 to higher versions. One thing I noticed is that we use parameters like this dotnet cake build.cake --Docker.Password=xxx but the newer versions of Cake say the parameter has invalid characters. Based on my test it is the dot that Cake doesn't like. Can somebody tell me why this was changed? Is there any workaround for that or there is no backward-compatible solution for this issue and should we refactor all of our variable names?

Thanks!
