The bug
When I run the code below, I get the following error:
ValueError: No valid option generated in #select! Please post a GitHub issue since this should not happen :)

To Reproduce

# doesn't work
guidance(
    "Hello, {{#select 'name'}}Alice{{or}}Bob{{/select}}",
    llm=guidance.llms.Transformers("gpt2"),
)()

# works
guidance(
    "Hello,{{#select 'name'}} Alice{{or}} Bob{{/select}}",
    llm=guidance.llms.Transformers("gpt2"),
)()
