描述

Related to #54 I am trying to do something similar with a for loop.

As an example if the for variable is a keyword this works

(render "{% for a in Amt %}{{a.attr.Ccy}}{{a.content.0}} {% endfor %}" 
    {:Amt [{:attr {"Ccy" "USD"}, :content ["0.010000000"]} 
           {:attr {"Ccy" "GBP"}, :content ["0.020000000"]}]})
 => "USD0.010000000 GBP0.020000000 "

However changing :Amt to "Amt" produces nothing

 (render "{% for a in Amt %}{{a.attr.Ccy}}{{a.content.0}} {% endfor %}" 
    {"Amt" [{:attr {"Ccy" "USD"}, :content ["0.010000000"]} 
            {:attr {"Ccy" "GBP"}, :content ["0.020000000"]}]})
=> ""

Should this be added as an enhancement to make processing consistent?

研究方向
Locate the code handling variable resolution in for loops, likely in the parser (e.g., `src/selmer/parser.clj`). Investigate how the for loop variable name is used to access the context map. The current behavior works with keywords but not strings. Determine if the fix involves converting string keys to keywords or adding a fallback lookup. See linked issue #54 for related context.
