propsal-typescript: support eval()

[frank-dspeed]

Problem

Typescript does not support eval so it is hard to get code into it programatical while coding we have the need to dynamical load and eval code in the ide

Solution

Support eval() and add the result to the ast

can at present be done via transpileFile inside a checker programm that will add that file to the ast
missing part is to have multiple ast views represenatations of the already created ast under diffrent conditions for example the same code can be in a file that use stric is enabled and if so it needs to be clear where that got started.

Motivation

imagin how cool that would be for api's lile the notebook api from vscode.
