Introduce scoped ajax placeholder variables, e.g. ‘placeholder ph { }’ declares ‘ph’ in the template.
They are scoped by template definition and template for loops.
Its value is of String-compatible type ‘Placeholder’.
The value is unique and deterministic based on template id.
This enables safe use of placeholders inside repeated templates and for loops without explicit placeholder name construction.

The next step is some refactoring in the analysis of template variables to correctly declare the placeholders. Currently the placeholder variable needs to be declared before use, which is too limiting as only a ‘for’ loop is a meaningful scope. The position of the placeholder should be flexible within that scope.

fixed scoping for placeholder names so that you can refer to the name above its definition and ‘for’ scopes names
