IDEs can 100% do this, too. The art of connecting to a running program using the debugger is just something folks stopped caring about.

This led a lot of programming environments to where batch loading of the code is basically required. But "image based" workflows are a very old concept and work great with practice. Some older languages were based on this idea. (Smalltalk being the main one that pushed this way. Common Lisp also has good support for interacting with the running system.)

It is a shame, as many folks assume everything has to be "repl" driven, when that is only a part of what made image based workflows work.
