Subject: Allow variables to be bound to complex expressions.
X-Git-Url: https://git.stderr.nl/gitweb?a=commitdiff_plain;h=9bffa6fd1ddc30866e7092ee477c0ee03a10a062;p=matthijs%2Fmaster-project%2Fc%CE%BBash.git

Allow variables to be bound to complex expressions.

Previously, variables (in let expressions for example) could only be bound
to single values. This enables them to be bound to for example tuples as
well.
