/usr/include/d/std/experimental/logger/core.d(487): Error:
safe function
'std.experimental.logger.core.defaultLogFunction!cast(LogLevel)cast(ubyte)128u.defaultLogFunction!().defaultLogFunction'

cannot call system function

  
'std.experimental.logger.core.Logger.memLogFunctions!cast(LogLevel)cast(ubyte)128u.logImpl!().logImpl'

in File std/experimental/logger/core.d
line 482 and 494 , should delete @safe.
