If expr yields #f
, display an appropriate error
message and throw an assertion-failed
exception.
Tell dmd that a key error with args has occured. This is the simplest way to cause caught error result in uniformly formated warning messages. The current implementation is not very good, though.
An alias for call-with-current-continuation
.
A simplistic implementation of the nonstandard, but popular procedure
call-with-escape-continuation
, i.e. a call/cc
for
outgoing continuations only. Note that the variant included in dmd is
not aware of dynamic-wind
at all and does not yet support
returning multiple values.
Evaluates the exprs, not going further if a system error occurs, but also doing nothing about it.
