can't import fsm package

[cosmos72]

Thank for spotting this :)
I'll investigate this bug

[cosmos72]

I've just rechecked this issue, and it seems to be working now (using Go toolchain <= 1.19, see issue #146).
Can you confirm?

I re-checked after (hopefully) fixing issue #146, and now import "github.com/looplab/fsm" fails with:

gomacro> import "github.com/looplab/fsm"
// debug: running "go get github.com/looplab/fsm" ...
go: added github.com/looplab/fsm v1.0.1
// debug: running "go mod tidy" ...
// debug: compiling plugin "/home/max/go/src/gomacro.imports/gomacro_pid_28645/import_1" ...
Converter.Type(): unsupported types.Type: *types.TypeParam

This is because gomacro does not yet know about go/types.TypeParam which represents a type parameter for a Go generic.
I'll add support for them as soon as I have time.

Commit 68a1200 skips generics when importing third-party packages,
because importing generics is not yet supported.

Now import "github.com/looplab/fsm" works:

gomacro> import "github.com/looplab/fsm"
// debug: running "go get github.com/looplab/fsm" ...
go: added github.com/looplab/fsm v1.0.1
// debug: running "go mod tidy" ...
// debug: compiling plugin "/home/max/go/src/gomacro.imports/gomacro_pid_19060/import_1" ...
