Handle libraries that use $ in function names

[Talinx]

What is it about?

Add options to the optimizer to handle libraries that use $ in function names without intending this as an instruction for the Qwik optimizer.

What's the motivation for this proposal?

Problems you are trying to solve:

• Use a library that uses $ in function names

Goals you are trying to achieve:

• Allow the usage of libraries that use $ in function names

Any other context or information you want to share:

I want to use the peggy library (https://peggyjs.org/). This library uses $ in function names, e. g. peg$SyntaxError. This causes errors in Qwik, e. g. Error: Value cannot be serialized in _.SyntaxError, because it's a function named "peg$SyntaxError". You might need to convert it to a QRL using $(fn): const peg$SyntaxError =...

The Qwik documentation states that it converts $ suffixes. Here it is not a suffix, yet it causes this error. (I guess $ as suffix is only the suggested style.) Maybe this is a bug in the optimizer and it should only treat $ as a special symbol when it is a suffix of the function name?

Proposed Solution / Feature

What do you propose?

The Qwik optimizer should be able to handle cases where $ is used in libraries that do not intend this as a special symbol for the optimizer. A solution could be one of these options:

• Do not treat $ as a special symbol in library code
• Have an option to add exceptions, e. g. that the $ symbol should not be treated as a special symbol for certain libraries or functions, e. g. specified by a Regex.

thanks @Talinx !
this sounds more like a bug than a feature
