String to expression node.

There are two problems with current geometric nodes: The first is that when I try to solve the equation with nodes, I need to create a lot of "Math node" to make a "cobweb" or "circuit board". If I want to use an expression, such as "# frame/360*pi", in addition to connecting a bunch of nodes, I can only create a new "Value" and type "#". Once I type "#", it's hard to copy in bulk like an asset.

So, I want to store the expression in "Sting node" and convert it to the evaluation result with a "String to expression node".
