Hi everyone. Doug recently checked in a handy new tool for streamlining error
handling when reading from streams. If you're in a situation where you need to
check a series of individual read operations for unexpected EOF, the new
"throw-on-eof" combinator can streamline the error checking for you. So this
sort of thing:
---
5 read
dup { [ not ] [ 5 length < ] } 1|| [ raise-an-error ] when
...
4 read
dup { [ not ] [ 4 length < ] } 1|| [ raise-an-error ] when
---
Can become instead:
---
[ 5 read ... 4 read ] throw-on-eof
---
