doh!
but I still think it makes the text needlessly formal.
When a string is evaluated, substrings matching variable-ref
shall be replaced by the value of variable-name. Only one pass
through the string shall be done.
consider a rewrite such as
When a string is evaluated, substrings matching variable-ref are
replaced by the value of variable-name. The string is only
passed through once.
is this text less binding for the implementor?
sorry about the stylistic quibbling, I'm just curious.
I think the formality is necessary. Consider this:
When a string is evaluated, substrings matching variable-ref
MUST BE replaced by the value of variable-name. The string
MUST BE passed through exactly once.
