[stringtemplate-interest] Problem with C# dictionaries

[brian.kejser at protexis.com]

Hi

Thanks. I understand what's going on now.

I don't agree with the implementation of this aspect of the string
template library. I believe the 'it' notation should always refer back to
the original object and not some deviation of the object. In order words,
I feel the following two templates should always render the same output?

$value.something$

$value:{$it.something$}$

In my opinion, this implementation contradicts the philosophy of string
template. That is, complexity and obfuscation are introduced into the
string template library for no apparent reason.

I would appreciate any comments on the above statements.

I am grateful for the work done on the string template library so please
don’t mistake my comments as an attack on the project members.

Thank you

$value$ is the dictionary. And ST# supports accessing the keys ("one" and
"two" in this case) as though they were attributes of the dictionary.

$value$ is still the dictionary. Template application returns a list of the
values in the dictionary i.e. ["testing", "more testing"]. So, $it$ would be
"testing" then "more testing" the second time. Strings don't have the
attributes 'one' or 'two'.
