IntersectionStatementParser

all takes a list of expressions and returns the first branch only if every one of them is true. It is the counterpart to any.

For template authors

{all(expression|expression|...):true message|false message}

Range checks are the common case, since if only compares two values at a time:

{all({n}>=100|{n}<=999):You picked {n}.|Pick a number between 100 and 999.}

Output · n = 52

Pick a number between 100 and 999.

Output · n = 282

You picked 282.

all, and, intersection

import { Interpreter, IntersectionStatementParser } from 'tagscript';
const ts = new Interpreter(new IntersectionStatementParser());

Both the parameter and the payload are required. Every expression is evaluated, then the results are AND-ed together, with no short circuit.
