Hi Ladislav and all,
>, I was wrong. Here is a (complicated, but working) version of the DEFAULT
>function, that can handle it:
I also was experimenting with do/next and this is my code. It try to handle
also return, throw, break.
isr?: function [blk [block!]][res][
while [not tail? blk][
either error? try [
error? catch [
error? do does [
error? loop 1 [
error? set 'res do/next compose [error? (blk)]
]
]
]
][
return true
][
if none? res [prin "control detected " return false]
blk: second res
res: none
]
]
false
]
block2: head insert tail copy [] try [first []]
isr? [1 2 first block2 3] ;==false
isr? [1 2 first block 3] ;==true
isr? [1 2 throw first block2 3] ;==control detected false
isr? [1 2 throw first block 3] ;==true
isr? [1 2 return first block2 3] ;==control detected false
isr? [1 2 return first block 3] ;==true
isr? [1 2 break/return first block2 3] ;==control detected false
isr? [1 2 break/return first block 3] ;==true
