[Newbies] Re: ByteString>>match: greedyness of * ??

[nicolas cellier]

This behavior is squeakish, other Smalltalk match differently:

VW:  '**' match: 'e'. "true"
gst: '**' match: 'e'. "true"

Anyway, this pattern matching is limited. How do you match a '*' itself?
I thought your example might be interpreted as an escape sequence, but 
no, there is no escape in this simple matching.

'**' match: '*'. "false"
'\*' match: '*'. "false"

Try VBregex or another regex package.
