Describe the bug

Template names in this format:

# 1.3.2.TryThis

Throw an error when called as a function:

# 1.3.1.NotUnderstoodMessaging
- I'm sorry, I'm not able to help with that. ${1.3.2.TryThis()}
- Sorry, that’s not something I can help with yet. ${1.3.2.TryThis()}
- Apologies, I don’t know how to do that right now. ${1.3.2.TryThis()}
- Unfortunately I can’t help you with that right now. Apologies. ${1.3.2.TryThis()}
- Sorry, that’s not something I can help with yet. ${1.3.2.TryThis()}
- Apologies, I don’t know how to do that right now. ${1.3.2.TryThis()}

Thanks Joe. Sorry for the block and hmmm.. It is indeed a bug. The workaround is to replace the pure numbers with letters between every two dots of template name.

The reason for this problem is that the format limits of template name and function name are different. The function name's format cannot cover all template name's formats.

The valid format of template name is

start with letter/number/_ and can only contains letter/number/./_

And the valid format of function name should meet

foreach(var part in expression.split('.')) 
{
    // part should start with letter/_ and can only contains letter/number/_
}

We will fix this issue as soon as possible.
