We did that in the 1980’s and the 1990’s on the Commodore 64 and the Amiga, only then the debugger was called a monitor and it was quickly discovered that programming in them was slow and error prone because they lacked the ability to recompute. That is how assemblers were invented: Turbo Assembler on the Commodore 64 and ASM-One, TRASH’M-One, Seka and MasterSeka on the Amiga. ASM-One and TRASH’M-One include an excellent debugger built natively into the integrated development environment, and stepping through the code after assembling it is a joy.
