learning mode: missing concepts

[ErikSchierboom]

In this issue, we can try to keep track of concepts that we feel should be taught in the syllabus and aren't yet.
I'd like to prioritize the missing concepts, as having a concept that improves the flow between existing concept exercises is way more important than adding a new, more advanced concept.

Missing concepts

The following list of concepts is ordered by importance, starting with the most important concepts:

• loops
• composite-types
• mutating-functions
• type-annotations
• type-inference (I think this goes well with type-annotations)
• char
• bitwise-operations
• vectorized-operators
• conversion
• promotion
• constructors
• mutable-composite-types
• abstract-types
• primitive-types
• type-unions
• sets
• symbols
• exceptions
• interfaces
• modules
• recursion
• tasks
• channels
• macros (this should probably be split up into multiple concepts)
• complex-numbers
• rational-numbers

Implemented concepts

• arithmetic-operators
• boolean-expressions
• boolean-logic
• booleans
• conditionals
• dictionaries
• docstrings
• emoji-symbols
• functions
• if-expressions
• integer-equality
• iterator-protocol
• kwdef
• matrices-introduction
• methods
• multiple-dispatch
• nothingness
• optional-arguments
• pairs
• predicates
• randomness
• regex
• short-circuit-evaluation
• string-literals-using
• strings
• ternary-operator
• unicode-identifiers
• using-macros
• vectors

See #563 for context

Take a look at https://gist.github.com/SaschaMann/3c77830daf2e933597fd3c181dcc4429

It might not be fully up-to-date but that was a chart I used in the past to keep track of what concepts we're covering and which concepts are missing.

From your list the key one to prioritise would be composite-types as that's a prereq for other concept exercises. Loops (esp. with a focus on loops being fast and not having to vectorise everything) would be nice to have but not strictly necessary. I'd also add mutating functions to the list so that people know what the bangs mean in function names (--> Elyse's Transformative Enchantments was my idea back then. Something about mutating the contents of an array)

Everything else in the list is nice to have but doesn't block any existing concept exercises from working.

Thanks a lot! I'll prioritize
