Here’s the deal: I’m sick of writing long scripts or being locked in certain cases to not being able to use dynamic features because I don’t know how to use things like eval on the left side of the equals

Here’s an example

```auto
base.mitem1y = mitem1._y
base.mitem2y = mitem2._y
base.mitem3y = mitem3._y

```

etc.

This should be in a for statement. However, I get errors (as I should) if I try using something like

```auto
base.eval("mitem"+i) = eval("mitem"+i)._y

```

Any nudges in the right direction is much appreciated!
