是否可以在 Nimrod 中使用函数指针?
我试过的是:
type fptr = (proc(int):int)
proc f(x:int): int =
result = x+1
var myf : fptr = f
echo myf(0)
但是当我尝试编译时,我得到:
Hint: added path: 'C:\Users\Peter\.babel\pkgs\' [Path]
Hint: used config file 'C:\Program Files (x86)\Nimrod\config\nimrod.cfg' [Conf]
Hint: system [Processing]
Hint: hello3 [Processing]
Error: internal error: GetUniqueType
