Feature request? input pattern

Hallo, i've been using inquirer for a while now and this it#s quite elegant (slim & flexible).

That said I never got to warm with the input prompt as it seems to slim to me 😅 Let's assume i want a number input, or a floating point input or a phone address input, currently with the input there#s no good way to archive it.

Let's assume a simple prompt:

> Your most loved float: ..., where the expected input is some float.

When using the input component a user can enter whatever he wants and the options I have to fix this are:

1. use transform to just discard any invalid characters visually -> afterwards "cleanup the input" (which can be quite hard as ppl might be using . or , or sprinkle spaces, letter etc)
2. use validate to ensure the input is valid after enter-press ... which is not so great either as you then have to start fixing the input

Imo it would be nicer, if there was a way to just directly specify an allowed input pattern.

What i usually end up doing is adding a custom input component which in essence is a copy of the current input with the addition of:

pattern?: RegExp;
patternError?: string;

inside of useKeyPress i then, just omit keys when the pattern would be invalidated:

if(!pattern.test(rl.line) {
      const line = rl.line;
      rl.clearLine(0);
      rl.write(line.slice(0, -1));
      setError(patternError);
} else {
// current event handling
}

I'm wondering if that would be a welcome addition to the project? I'm not sold on the naming of paramters. For me the RegExp was sufficient, but perhaps a more generic: discardKey: (key, line) => {} could be considered
