GNAT, specifically, has modes that are closer to what Python
does. When GNAT "just checks" (-gnatc), or when the programmer
asks for "minimal recompilation" only (-m), these and other
switches will speed things up.
Separate compilation also reduces the number of units that
need to be compiled again, e.g. when unit B has not changed
but unit A has, then only unit A needs to be compiled.
OTOH, intense checking or compiling Java or Swift in Eclipse or
Xcode happens at all times, so that one doesn't notice all
the translation work---but the processor does! As Python is
finally getting an optional type system as part of the written
language, not surprisingly, type checking is expensive for this
Python and translation takes more time.
