-# Notes on go
-Go compiles into native machine code.
-Go handles Unicode natively thus any character can be used in a string.
-Divided into packages, where a package is sort of a library, except for main which defines an executable.
-Import declarations **must** follow the package declaration.
-Function declarations: `func <name> (<param list>) (<result list>)`. No semicolons, unless multiple statements on 1 line.
-`gofmt` mandatory. `goimports` (`golang.org/x/tools/cmd/goimports`) manages imports.
-Slices are dynamically sized arrays that can be accessed `s[i]` or a subset can be taken `s[i:j]`. Indexing: half-open (starts at 0). `s[i:j]` yields i through j-1. Either can be omitted.
-
-Convention: comment describing package preceding package declaration.
-
-Variables initialised to "zero value".7689
-String concatenation via `+` char.
-Supports assignment operators, e.g `+=`, `*=` etc
-Short-hand variable declaration requires no type, it is inferred of the value `:=` **only allowed in a function**
-
-For-loop structure:
-```
-for initialization; condition; post {
- // code
-}
-```
-Either part can be left away with different semantics.
-All parts gone: loop forever.
-Only condition is like a while x == true;
-`range` keyword to loop over a slice or array with `for index, arg := range slice`
-
-`_` is the blank identifier, thus above if we don' need the index we can put `_`.
-
-**Type assertion**
