Valence allows for structural ambiguity: a single line of code can have multiple trees. This is possible because each sign is a homonym with different readings depending on context (as command vs expression, as which sign is a parameter for which, etc). Brackets allow for more specificity when needed. When run, every possible interpretation of the program runs side-by-side.
