[Hecl-devel] Fixed {a [ b} bug... maybe

[David W. <dav...@gm...>]

Hi,

I've been distracted with other things as of late, but I wanted to get
back on track with Hecl.

One thing that I wanted to fix up is [square braces] inside {curly braces}

For example:

set foo {a [ b}
set bar {a \[ b}

And so on.  Tcl does something kind of strange in the second case if
you treat $bar as a list - it does a second round of backslash
quoting, so that

lindex $bar 1
gives you [ instead of the literal \[ you might expect.

I decided to make Hecl give you back the literal \[ .  Although I
don't recall the exact details, I believe that this was the conclusion
we came to on the list, although my memory is a bit fuzzy, so I may be
wrong, so please have a look and a think...
