The regex was using \S+ to match the comma between the filters
arguments, but would continue to match idependent quote characters and
filter separators. This can result in multiple filters being interpreted as
a single one with many arguments.
When a continue or break statement is executed it pushes an interrupt to a
stack in context. If any non-handled interrupts are present blocks will cease
to execute. The for loop can handle the most recent interrupt in the stack.
I had accidentally read slice_collection_using_each as using to as an
inclusive limit rather than exclusive, and no tests covered the offset or
limit parameters.
A simple attempt, but basically it shifts the parsing of the right hand side of the assign from a simple context lookup to using the Variable parser (that includes filters). Fixes#79.
