Another recursion problem

[tavmem]

$ rlwrap -n ./k
kona      \ for help. \\ to exit.

   g:{a:x; {:[x=0; a:x; g(0)]}a; a}
  g 2
0

   g:{a:x; {:[x=0; a:x; _f(0)]}a; a}
  g 2
2

This case is discussed in some detail in the comments for closed issue

521: Recursive call overrides earlier data.

I'm setting it up as a separate issue since:

• It was not fixed
• Don't want to forget it

[tavmem]

From another angle:

  g:{a:x; if[x=0; a:x]; if[~x=0; g(0)]; a}
  g 2
2
