v0.2.15

New features

• Add assert(Fun, Type, Str) for asserting that the code throws the given exception. The type must be subtype of Exception.
• Add namespace net
• Add networking c_sockaddr, c_sockaddr_un, c_sockaddr_in
• Add networking functions: socket(), bind(), listen(), accept(), recvfrom(), send()
• Add networking constants: SOCK_STREAM, SOCK_DGRAM, SOCK_RAW, MSG_OOB, MSG_PEEK, MSG_WAITALL (all prefixed with C_)
• Add Not type and support in pattern matching
• Add env: option to pass environment when running external programs
• Add ensure(Int, NumRange)
• Add last(Eachable1, Any), the counterpart of first()
• Add skip(Iter, Any) - skip elements matching the pattern
• Add skip(Iter, Int) - skip given number of elements
• When a function is called from CLI, the output is now displayed using experimental echo_cli()
• Add AWS2::regions(CommandsPipeline, Arr)
• Add IfExists pattern for optionally present fields
• Add before_first(Str, Str) - get the piece before first occurrence of the delimiter
• Add after_last(Str, Str) - get the piece after the last occurrence of the delimiter

Fixes and improvements

• Add UndefinedUpVar exception, thrown when accessing undefined "upvar"
• Following types now inherit from Error, not Exception: NotImplemented, ReadFail, RequireFail, MainFail
• Experimental syntax - allow many additional elements x.HERE and x::HERE
• Fix and improve documentation
• Improve inspect()
• Add regs parameter to AWS2::regions(Fun)
• $(log: ...) can now take Str to prefix the message
• Improve retry() logging
• Improve Time(Str)

Deprecated

• is_subtype(Type, Type) is now deprecated, use <= operator, example: T1 <= T2. Solves #391.
• typeof(Any) is now deprecated, use Type(Any) instead.
• x \ f syntax is now deprecated, use x.f() and x.{...} instead.

Misc

• GCC 9 on macOS is not supported anymore - it's broken
