Since we use a recursive descent parser for the vimscript implementation of maktaba#json#Parse without setting 'maxfuncdepth', we're subject to vim's default recursion depth and can only parse up to a depth of ~&maxfuncdepth/2.

:echo maktaba#json#Parse('[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]')

E132: Function call depth is higher than 'maxfuncdepth'

We should bump 'maxfuncdepth' up to some very high number in maktaba#json#Parse and maktaba#json#Format and restore it after our recursion completes.
